pgsql: Rename static function to avoid conflicting names

Rename static function to avoid conflicting names

Commit a4fd3aa719e moved setup_cancel_handler out of psql and
exporeted it as a global function. While pg_dump isn't using
the header it's exported in, having a conflicting name still
risks causing confusion when grepping the code for callsites,
so rename the static function in pg_dump to avoid this.
