build: ruby: Add support for tarball and directory sources.
Previously, the Ruby build system only knew how to work with gem archives, which made it difficult to build unreleased gems from a Git repository or released gems in tarball form. * gnu/build/ruby-build-system.scm (gnu:unpack, gem-archive?): New procedures. (unpack): Use GNU build system unpack phase for non-gem sources. (build): Rebuild the gemspec iff the source is a gem archive. * guix.texi ("ruby-build-system"): Mention that tarballs and directories are acceptable.
