For AARCH64 ILP32, sigset needs to be an array of unsigned long long as
it needs to be 64bit to match AARCH64 lP64.

* sysdeps/unix/sysv/linux/bits/sigset.h: Include bits/types.h.
(__sigset_inner_t): New typedef.
(_SIGSET_NWORDS): Use __sigset_inner_t instead of unsigned long.
(__sigset_t): Likewise.
(__sigmask): Likewise.
(__sigword): Likewise.
(__SIGSETFN): Likewise.

Is there a reason this shouldn't just use __syscall_ulong_t?
