[CONJ-1053] Make the JPMS requirement on waffle-jna static

[A248]

The waffle-jna dependency is needed only when Windows GSSAPI authentication is used. In a previous commit, the static was incorrectly removed, making the dependency a hard requirement when running on JPMS.

However, maven is not the same as JPMS. An optional dependency via Maven is not the same as requires static in JPMS. They serve entirely different purposes. By removing requires static, you are saying that all deployments must have waffle-jna present on the module path.

Re-adding requires static will not affect existing clients using MariaDB Connector-J. If they used waffla-jna before, they will continue to use it after this change.
