[S390] allow usage of string functions in linux/string.h
In introducing a trivial "strstarts()" function in linux/string.h, we
hit the following error on s390:
In file included from include/linux/bitmap.h:8,

include/linux/string.h:124: error: implicit declaration of function 'strlen'
include/linux/string.h:124: warning: incompatible implicit declaration of built-in function 'strlen'
Because when including asm/string.h from arch/s390/lib/string.c we
don't declare the string ops we are about to define, and
linux/string.h barfs.
The fix is to declare them in this IN_ARCH_STRING_C case, but in
general I wonder if there's a neater fix.
