SH: define syscall_get_arch() for superh
This patch defines syscall_get_arch() for the um platform. It adds a
new syscall.h header file to define this. It copies the HOST_AUDIT_ARCH
definition from ptrace.h. (that definition will be removed when we
switch audit to use this new syscall_get_arch() function)

linux-xtensa, x86
We have a function where the arch can be queried, syscall_get_arch().
So rather than have every single piece of arch specific code use and/or
duplicate syscall_get_arch(), just have the audit code use the
syscall_get_arch() code.
