[kvm-unit-tests PATCH v2 4/6] s390x: fix compile of interrupt.c

A future commit will include interrupt.h from sie.c.

Since interrupt.h includes mem.h, but sie.c does not include facility.h,
this will lead to the following compile error:

In file included from lib/s390x/interrupt.c:10:
/home/nrb/kvm-unit-tests/lib/asm/mem.h: In function ‘set_storage_key_mb’:
/home/nrb/kvm-unit-tests/lib/asm/mem.h:42:16: error: implicit declaration of function ‘test_facility’ [-Werror=implicit-function-declaration]
42 | assert(test_facility(8));
| ^~~~~~~~~~~~~

Add the missing include in interrupt.h
