SH: define syscall_get_arch() for superh
This patch defines syscall_get_arch() for the superh platform. It does
so in both syscall_32.h and syscall_64.h. I'm not certain if the
implementation in syscall_64.h couldn't just be used in syscall.h as I
can't really track the setting of CONFIG_64BIT...
This way is safe, but we might be able to combine these if a superh
person were able to review...
[v2]
fixed indentation stoopidity (Sergei Shtylyov)
use AUDIT_ARCH_SH instead of EM_SH
