Eric W. Biederman 6487d1dab8 ptrace: Return the signal to continue with from ptrace_stop 
The signal a task should continue with after a ptrace stop is
inconsistently read, cleared, and sent.  Solve this by reading and
clearing the signal to be sent in ptrace_stop.

In an ideal world everything except ptrace_signal would share a common
implementation of continuing with the signal, so ptracers could count
on the signal they ask to continue with actually being delivered.  For
now retain bug compatibility and just return with the signal number
the ptracer requested the code continue with.
