Fix support for GraalVM 22.2

This commit adds a workaround for GraalVM 22.2 native-image builder running
on module path. Because Micronaut uses features which use internal APIs (and
no workaround for that), building on 22.2 fails. This commit adds a flag
which will let users build by adding a module export.
