[kvm-unit-tests PATCH 1/3] s390x: Add SPDX and header comments for s390x/* and lib/s390x/*

[Janosch Frank <frankja@linux.ibm.com>]

Seems like I missed adding them.

The s390x/sieve.c one is a bit of a head scratcher since it came with
the first commit but I assume it's lpgl2-only since that's what the
COPYRIGHT file said then.
