makefile: adjust tv build for versioning changes

Updates tailscale/tailscale#18969

gradle now treats tv and phone builds as the same thing - simply
changing the last digit of the android version.   Adjusting the
makefile accordingly so we're building the right thing, and looking
in the right places for the build output.
