Makefile.am: Link `libmetric` and `liboconfig` into `libplugin_mock`.

This allows us to remove these as direct dependencies from many tests.

Because `libmetadata` is linked into `libmetric`, it can also be removed.

Overall this will make link more things that are in the daemon into
`libplugin_mock`, making linking unit tests simpler.
