the old style sigprocmask system call correctly without corrupting
memory when we copy out the new (larger) signal mask into the user
provided old (smaller) signal mask.

While doing so, fixed bug #93328, by using the right sized types in
sigprocmask(), and converting them as necessary. Added a regression test for
it too.
