Configure gcc:pkcs11 CI job with "--disable-warn-error"

Configure gcc:pkcs11 CI job with "--disable-warn-error"

"--disable-warn-error" ./configure option disables compiler warnings.
This ensures that the job will not fail because of warnings (e.g., array
inconsistencies in lib/isc/sha2.c) we don't want to fix on BIND 9.11
because the version is in security-fixes-only mode.
