[meta-virtualization] [PATCH] ruby.bbclass: WARNING Fix

[Li xin]

When build the recipes which inherit ruby,WARNING will occur as following:
WARNING: QA Issue: mixlib-log: Files/directories were installed but not shipped in any package:
  /usr/lib/ruby/gems/2.2.0/build_info
  /usr/lib/ruby/gems/2.2.0/extensions
Please set FILES such that these items are packaged. Alternatively if they are unneeded,
avoid installing them or delete them within do_install. [installed-vs-shipped]
So modify ruby.bbclass
