[pgpool-committers: 10311] pgpool: Fix pool_signal.

[Tatsuo Ishii]

Fix pool_signal.

Previously pool_signal did not set SA_RESTART flag.  Thus any system
calls interrupted by a signal does not restart. Some of our code are
prepared so that they restart if a system call is interrupted by a
signal. But not sure all places are prepared too. So add the
flag. Note, PostgreSQL always uses the flag.
