sparc: implement is_32bit_task
We are currently embedding the same check from thread_info.h into
syscall.h thanks to the way syscall_get_arch() was implemented in the
audit tree. Instead create a new function, is_32bit_task() which is
similar to that found on the powerpc arch. This simplifies the
syscall.h code and makes the build/Kconfig requirements much easier
to understand.
