* fhandler.h (PIPE_ADD_PID): Define new flag.

* pipe.cc (fhandler_pipe::create): Don't indiscriminately add process id to
every pipe since some pipe names (fifo, tty) don't need it.
* sigproc.cc (sigproc_init): Pass PIPE_ADD_PID to fhandler_pipe::create to
ensure that pid is always part of sigwait pipe name.
