Remove "out" special case handling from FindEmulator

We removed the special casing of $OUT_DIR from our findleaves commands
to fix problems where $OUT_DIR was named the same as a real directory.
But now TEST_FIND_EMULATOR (and regen) is broken, since the real command
finds out/Android.mk, but the emulated version does not. Since we're
already traversing output directories that aren't called "out", just
remove the "out" special casing from the find emulator.

This raises the time to init the find emulator from 0.85s to 1.12s on my
machine with one product built. But this only happens when you're about
to read all of the makefiles anyways, not during regen. The node count
goes from 683196 to 894396.
