This reverts commit 7e3a596a63.
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.
