 [Backport #20516]

	Clear runtime dependencies if default gems is specified.

	The current build system uses runtime dependencies from only
	`.bundle` directory. We shouldn't install runtime dependencies
	from rubygems.org when `make test-bundled-gems` is invoked.

	Fixed dependencies list format

	Re-use strscan with ruby repo
