[rubygems/rubygems] Make the test_build_extensions more predictable
The test_build_extensions make assumptions about return value of Gem.install_extension_in_lib. Givent that RubyGems allow to override this method via defaults.rb / operating_system.rb, this test might not always pass. This change makes sure that the Gem.install_extension_in_lib is predictable.
