Justin Cormack c7bf74a6ab Revert "Block obsolete socket families in the default seccomp profile"
This reverts commit 7e3a596a63fd8d0ab958132901b6ded81f8b44c0.

Unfortunately, it was pointed out in https://github.com/moby/moby/pull/29076#commitcomment-21831387
that the `socketcall` syscall takes a pointer to a struct so it is not possible to
use seccomp profiles to filter it. This means these cannot be blocked as you can
use `socketcall` to call them regardless, as we currently allow 32 bit syscalls.

Users who wish to block these should use a seccomp profile that blocks all
32 bit syscalls and then just block the non socketcall versions.
