dev-db/pgagent: new patch to fix building against postgres-10.x.

The pgAgent build system didn't support a two-digit version of
postgres, so pgagent failed to build against (for example)
dev-db/postgresql-10_beta3. This has been fixed upstream but not yet
released, so this commit cherry-picks that upstream commit as a patch
and adds it (in-place) to the latest pgagent-3.4.0-r2.ebuild.

Gentoo-Bug: 625878

Package-Manager: Portage-2.3.6, Repoman-2.3.1
