Disable warnings for unknown modules in package-modules.mk

We've had these warnings for a while, but we've still got a lot of
warnings that people have been trained to ignore. Lets just silence them
for now.

The Merged-In is just a random change from AOSP that isn't in pi-dev, to
stop this from being merged to master, where I'm just fixing the
warnings.
