Drop %post chown rpcuser /var/lib/nfs/statd
Digging through the git history quickly, this seems to be a workaround
for an ancient upgrade issue. We really shouldn't be
doing this on new installs, and really not on on every upgrade either.
The particular reason I'm making this change is that rpm-ostree
explicitly errors out when scripts fail (because we can), and this
will fail in an rpm-ostree environment as the real `/var` is not accessible
to scripts.
