signals, sched: Change all uses of JOBCTL_* from 'int' to 'long'
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.
