The upstream test runner has changed enough that the way Android was
shimmed into it was no longer compatible. This adapts our test runner
to the new APIs for cross-compiling and remote execution.
There's probably a fair amount of dead code in the Android test
runners now (or at least some code that should be made dead). I'll
clean it up in a later patch, but want to get us up and running for
now.
The NDK test runner will need to be updated as well. There aren't any
continuous runs for that, so that will be fixed in a follow up as
well.
