s390/purgatory: do not build purgatory with kcov, kasan and friends

[ Upstream commit c23587c92f6e3260fe3b82bb75b38aa2553b9468 ]

the purgatory must not rely on functions from the "old" kernel,
so we must disable kasan and friends. We also need to have a
separate copy of string.c as the default does not build memcmp
with KASAN.
