Support x64 Android

Also updated paths to depend on updater.h and libupdater.a
from third_party directly now that DEPS knows how to pull
down updater for us.

We still don't build updater from gn/ninja yet (we should)
but this at least fixes the ninja null build to be null again
previously it was rebuilding common.shell.o every time,
unclear why.
