eclass/ruby-fakegem.eclass: add method to indicate extensions are installed

Add a public method ruby_fakegem_extensions_installed to add the
marker that rubygems uses to determine if extensions have been
installed. We were already adding this as part of the extensions code,
but rubygems also expects this to be present for extensions that we
either ignore or handle differently. Without this marker rubygems
3.2.22 and newer will ignore this gem.
