Subject: [PATCH] Revert rubygems tempdir check

This check was added to check if other tests still remain tempdir, and these tests do on Windows.

* `TestGemCommandsSetupCommand#test_destdir_flag_does_not_try_to_write_to_the_default_gem_home`
* `TestGemInstaller#test_install_build_root_when_gem_home_not_writable_does_not_fallback_to_user_install_inside_build_root`

Also some tests fail due to too long path names.
