Fix pgpool_setup to deal with PostgreSQL 9.1.

"---data-checksums" was unconditionally added to initdb's arg but
PostgreSQL 9.1's initdb does not have the option. To solve the issue,
internal variable $PGVERSION now represents "major version" * 100:
e.g. 120 for PostgreSQL 12.x (including 12beta), 91 for PostgreSQL
9.1.x, so that pgpool_setup can check if the option can be added to
initdb options.
