build: glibc has removed rpc headers and rpcgen in Fedora28, use libtirpc

Other Linux distributions are doing the same; some others have already
done so.

Switch to libtirpc(-devel) and unbundled rpcgen packages. For now
rpcgen is still provided by the glibc-rpcgen RPM, but rpcsvc-proto's
rpcgen subpackage is available now but will not be used until
glibc-rpcgen is retired. (note, rpcsvc-proto's rpcgen is just named
rpcgen-...rpm. I.e. not rpcsvc-proto-rpcgen.) Right now either one
will satisfy the BuildRequires: rpcgen.

Also, when a .spec file has
  BuildRequires: foo-devel
it is not necessary to also have:
  BuildRequires: foo
or even:
  BuildRequires: foo foo-devel

The foo-devel package has a dependency on foo, which will install foo
automatically. It's usually also not necessary to have a corresponding
  Requires: foo
as the rpmbuild process will also automatically determine the
install-time dependencies.

And other minor glusterfs.spec.in cleanup of ipv6-default, including
sorting the argument definitions because the comment says "keep them
sorted" (Though nobody appears to have ever sorted them in the first
place.)
