This restores 3.0 behavior and goes back to not formatting executables
by default on `gem update --system`. This is friendlier for jruby and
doesn't really affect OS packagers.

Currently `gem uninstall --all` shows the following incorrect message
after completion:
```
INFO: Uninstalled all gems in
```
Now it shows something that actually makes sense like:
```
INFO: Uninstalled all gems in /home/deivid/Code/rubygems/tmp/test_rubygems_6986/gemhome
```

`@host` _could_ be `nil` at this point, but only if all the conditions
above for setting `@host` were `nil`. In that case, it is guaranteed
to `default_gem_server` metadata is `nil` since it's one of the
branches in that condition. So this code would just be setting an
already `nil` variable to `nil`. Hence, not needed.

This block was a branch and variable heavy way of saying use the
user-provided host if available, or fall-back to the default host if
none of the other options match. IMO the resultant single-if condition
is clearer in intentions

This condition is too restrictive in my opinion. If a user has a pre
version of rubygems installed, she should be fully responsible for it,
and we shouldn't restrict any functionality.
Also, why is a new prerelease disallowed but an old prelease allowed, or
why is 2.0.0.rc2 explictly whitelisted? I believe this kind of
exceptions are one more reason to actually permit this.
