Tim Schumacher edbffb3c7a Kernel: Unblock SignalBlocker if a signal was just unmarked as pending ...

When updating the signal mask, there is a small frame where we might set
up the receiving process for handing the signal and therefore remove
that signal from the list of pending signals before SignalBlocker has a
chance to block. In turn, this might cause SignalBlocker to never notice
that the signal arrives and it will never unblock once blocked.

Track the currently handled signal separately and include it when
determining if SignalBlocker should be unblocking.
