Search for CompOsPayloadApp/EmptyPayloadApp with extensions

There are Google variants of these apps internally, but currently
they use the `stem` property to rename their final apk to match the
non-google version. This is a problem because these two modules end up
conflicting if they're both exported to make. Currently, the fact that
they're included in apexes hides that they're exported to make, but
we're changing that behavior.
