s390: add missing header includes for type checking

Add missing include statements to make sure that prototypes match
implementation. As reported by sparse:

arch/s390/crypto/arch_random.c:18:1:
  warning: symbol 's390_arch_random_available' was not declared. Should it be static?
arch/s390/kernel/traps.c:279:13: warning:
  symbol 'trap_init' was not declared. Should it be static?
