Namely, those generated under `/tmp`.
The previous approach was brittle and broken in the case of ruby-core,
because under that setup, the current folder is in the original
`$LOAD_PATH`, and dummy features are created under `./tmp`, so they were
failing to be reset.
This was guaranteed by our gitignore setup where a `tmp/` folder is
always present right after cloning the repository, but was not
guaranteed under the ruby-core setup.
This alternative approach should always work.
In `ruby-head` (where system rubygems already has the `XDG` standard
implementation), some tests currently depend on the presence of a
`~/.gem` folder in the home of the user that runs the tests. If that
file is present, tests pass, otherwise they don't.
For example, the following passes if you have a `~/.gem` folder but
fails otherwise with:
```
$ rake TESTOPTS="--name=/TestGemCommandsGenerateIndexCommand#test_execute$\|TestGemCommandsUpdateCommand#test_execute_user_install/ -v"

This is because the very initial `require` of the default `did_you_mean`
gem that ruby does on startup runs _before_ the global `setup` hook of
our tests run. During this require `Gem.data_home` and its value is
memoized to a path in the real users home (not the fake user's home that
our tests setup, since that code hasn't run yet). Then that memoized
value is used when looking for the default folders to look for gems, and
since there's no `~/.gem` folder, its value is actually used as part of
the `Gem.user_dir` folder in `Gem::Specification.dirs` (this is how
we've approached backwards compatibility for the `XDG` feature). That
means dummy test gems with the `--user-install` flag are installed to
global, real locations and everything is messed up.
This commit fixes the issue by resetting the `Gem.data_home` value in
case it has already been memoized.
This is a default gem on jruby, which ships with a rubygems plugin,
which prints warnings all over the place during our tests.
This plugin is unnecessary from our tests, so I disable it through the
`JARS_SKIP` environment variable provided by this gem.

This requirement was introduced 14 years ago in
7ce7039b390440754954df5efea619e9f57ef823, and I don't think it's
necessary anymore. I made several tests introducing UTF-8 characters in
gemspec files and generating indexes out of them, and couldn't find any
issues. Gemspecs are read with UTF-8 encoding these days.
To make tests more deterministic, since `Dir.tmpdir` sometimes will
return the current directory dependending on the writability of other
paths, and in that case since the current directory is changed by our
tests, tests can fail.
Force a local tmp folder instead, which will always be writable.

Our tests are now guaranteed to not work on older versions of minitest,
so I don't think we should swallow this activation error because it will
make it very clear for the user what the problem is if she has a
minitest version not satisfying the requirement.
