tests: skip seccomp-strict.test and prctl-seccomp-strict.test on x32

As x86_64 kernel does not support x32 syscall numbers in
SECCOMP_MODE_STRICT, skip affected tests on x32.

* tests/seccomp-strict.c (main) [__x86_64__ && __ILP32__]: Bail out
using error_msg_and_skip.
* tests/prctl-seccomp-strict.c: Likewise.
