Disallow masking SIGKILL and SIGSTOP in user space
...
According to the Linux man pages[1], "It is not possible to block SIGKILL
or SIGSTOP. Attempts to do so are silently ignored." This patch ensures
compliance by explicitly removing SIGKILL and SIGSTOP from the signal
mask in the `MaskOp::SetMask` operation of the `rt_sigprocmask` syscall.
