init/Kconfig: make COMPILE_TEST depend on !S390

commit 334ef6ed upstream.

While allmodconfig and allyesconfig build for s390 there are also
various bots running compile tests with randconfig, where PCI is
disabled. This reveals that a lot of drivers should actually depend on
HAS_IOMEM.
Adding this to each device driver would be a never ending story,
therefore just disable COMPILE_TEST for s390.

The reasoning is more or less the same as described in
commit bc083a64 ("init/Kconfig: make COMPILE_TEST depend on !UML").
