This adds support for s390 to the seccomp selftests. Some improvements
were made to enhance the accuracy of failure reporting, and additional
tests were added to validate assumptions about the currently traced
syscall. Also adds early asserts for running on older kernels to avoid
noise when the seccomp syscall is not implemented.

This imports the existing seccomp test suite into the kernel's selftests
tree. It contains extensive testing of seccomp features and corner cases.
There remain additional tests to move into the kernel tree, but they have
not yet been ported to all the architectures seccomp supports:
