[pgpool-committers: 10500] pgpool: Replace PostmasterRandom() with pg_strong_random().

[Tatsuo Ishii]

Replace PostmasterRandom() with pg_strong_random().

Our PostmasterRandmon() was imported from PostgreSQL long time ago (in
2016). In the same year PostgreSQL replaced PostmasterRandmon() with
pg_strong_random()(src/port/pg_strong_random.c). This commit follows
it.

pg_strong_random() looks better than PostmasterRandmon(), since it's
more secure and portable. Moreover no initialization is necessary.
