We need libcutils to include liblog

For some prebuilts were built against libcutils with liblog in it.
Unfortunately that means in the future if someone checks in prebuilts
that are built against libcutils and they don't explicitly link against
liblog, they will again prevent us from removing liblog from libcutils.
