[1/2] libselinux: versioned ruby pkg-config and query vendorarchdir properly

Commit Message

Gentoo and Arch have pkg-config entries for "ruby-$(RUBYLIBVER)" but not
for "ruby". Check if that exists first then fall back to plain ruby if
it does not.

The ruby install paths were incorrect. Fedora 20 installed to
/usr/lib64/ruby/vendor_ruby/, Arch needs it to be vendor_ruby as well,
site_ruby does not work. Thanks to Nicolas Iooss for the correct way to
query for the path.
