c56fb6564dcd ("Fix a misaligned load inside ptrace_attach()") makes
jobctl an "unsigned long".  It makes sense to have the masks applied
to it match that type.  This is currently just a cosmetic change, but
it will prevent the mask from being unexpectedly truncated if we ever
end up with masks with more bits.

One instance of "signr" is an int, but I left this alone because the
mask ensures that it will never overflow.
