s390/purgatory: Add -Wno-default-const-init-unsafe to KBUILD_CFLAGS
[ Upstream commit b4780fe4ddf04b51127a33d705f4a2e224df00fa ]
Add -Wno-default-const-init-unsafe to purgatory KBUILD_CFLAGS, similar
to scripts/Makefile.extrawarn, since clang generates warnings for the
dummy variable in typecheck():
