Remove --quiet option from pg_amcheck

Using --quiet in combination with --no-strict-names didn't work as
documented, a warning message was still emitted. Since the --quiet
flag was working in an unconventional way to other utilities, fix
by removing the functionality instead.

Backpatch through 14 where pg_amcheck was introduced.
