Fix native compilation for MariaDB java client 3.5

1. Authentication plugins now have factories, so the substitution for
   PAM had to change.
   See mariadb-corporation/mariadb-connector-j@734e7de#diff-dc08764181b86cf19de46936c85631d8c3501d4fe3b198b610bc152505960327L40-L41
2. Configuration parsing now reflectively calls methods on the builder,
   instead of accessing fields directly, so we must enable method
   reflection.
   It would seem field reflection is still necessary for other reasons.
   See mariadb-corporation/mariadb-connector-j@a12ae9f#diff-2573c2b3bd0420719971212a9d3d2268d8de6b1de6c54deb77e50f007501fe6eL949-R766
