pgsql: Skip \password TAP test on old IPC::Run versions

Skip \password TAP test on old IPC::Run versions

IPC::Run versions prior to 0.98 cause the interactive session to time out,
so SKIP the test in case these versions are detected (they are within the
base requirement for our TAP tests in general).  Error reported by the BF
and investigation by Tom Lane.
