Daniel Gustafsson c3333dbc0c Only perform pg_strong_random init when required
The random number generator in OpenSSL 1.1.1 was redesigned to provide
fork safety by default, thus removing the need for calling RAND_poll
after forking to ensure that two processes cannot share the same state.
Since we now support 1.1.0 as the minumum version, and 1.1.0 is being
increasingly phased out from production use, only perform the RAND_poll
initialization for installations running 1.1.0 by checking the OpenSSL
version number.

LibreSSL changed random number generator when forking OpenSSL and has
provided fork safety since version 2.0.2.

This removes the overhead of initializing the RNG for strong random
for the vast majority of users for whom it is no longer required.
