Improve version reporting in pgbench.

Commit 547f04e73 caused pgbench to start printing its version number,
which seems like a fine idea, but it needs a bit more work:
* Print the server version number too, when different.
* Print the PG_VERSION string, not some reconstructed approximation.

This patch copies psql's well-tested code for the same purpose.
