pkg: pkg_verify_dependency(): add return error flags pointer. 

presently, three error flags are defined:

PKG_ERRF_OK: everything went fine (no error)

PKG_ERRF_PACKAGE_NOT_FOUND: a graph node couldn't be verified because there was no
                            database entry for it

PKG_ERRF_PACKAGE_VER_MISMATCH: a graph node couldn't be verified because the entry
                               in the database did not match versioning constraints
