opie-mediaplayer1: Start measures to get rid of circular package dependencies.

* The idea is simple and standard: introduce a node in graph "above" current ones,
and make it depend on existing nodes, instead of them depend on each other.
Thus, we'll have opie-mediaplayer1-core & opie-mediaplayer1-plugins*, and
opie-mediaplayer1 virtual package above them.
* Step 1: rename existing opie-mediaplayer1 recipe to opie-mediaplayer1-core
(to be edited later).
