[PATCH 3/3] s390/Kconfig: drop select of KEXEC

No proof is found to require that S390 architecture has to select
KEXEC. At least from my testing at below, dropping select of KEXEC won't
impact anything.

===testing 1===
CONFIG_CRASH_CORE=y
CONFIG_KEXEC_CORE=y
CONFIG_CRASH_DUMP=y
===

===testing 2===
CONFIG_CRASH_CORE=y
CONFIG_KEXEC_CORE=y
CONFIG_KEXEC_FILE=y
CONFIG_CRASH_DUMP=y
===

So drop the select of KEXEC now.
