xfsprogs: remove retpoline support

When it came up that xfsprogs was using retpolines by default,
the gcc folks inside Red Hat expressed ... alarm.  I'm not sure
of all the details, but I think the concern was that userspace
support for this is not really quite baked.

Unless/until there is a demonstrated side-channel which would
warrant retpolines here, let's just remove it for now.
