Log Message:
Stop resetting signal context on a trap signal under a debugger

In case of a crash signal, notify debugger immediately passing the signal
regardless of signal masking/ignoring.

While there pass signals emitted by a debugger to debuggee. Debugger calls
proc_unstop() that sets p_stat to SACTIVE and this signal wasn't passed
to tracee.

This scenario appeared to be triggered in recently added crash signal ATF
ptrace(2) tests.
