Title: Add USEPKG variable for Makefiles

Currently pkg/USING says one should use `EXTERNAL+=$(RIOTBASE)/pkg/` to enable PKG modules. Using this line the PKG will be compiled but not linked.

This change adds a USEPKG variable to be used like `USEPKG += `, which looks less clumsy and gets the PKG linked in the binary.
