[PATCH] selftests/seccomp: Unconditionally define seccomp_metadata

[Luke Nowakowski-Krijger]

There are conflicts between glibc system headers sys/ptrace.h and
linux/ptrace.h that can likely cause seccomp_metadata not be
defined depending on what version versions are installed, leading
to compile errors.

A solution to make this test more resitant to these system header
differences is to rely on defintions inside of the file by
unconditionally defining seccomp_metadata and removing the
linux/ptrace.h include where a defintion of seccomp_metadata
exists for certain headers.
