reverse order of data construction, to keep Cpanel::JSON::XS out of META.*

We need to use META_ADD and make that data look how we want it to be in
META.*, then use that to construct PREREQ_PM etc (META_ADD rather than
META_MERGE means that this data, based on the state of the releaser's machine,
won't be added to META.*

Of course, if we generated META.* via a different mechanism than EUMM, we
wouldn't have to go to all this trouble...
