Android Docker: give the docker build its own output tree

Again, this is relevant for developers that do local docker android
builds, and normal android builds. A normal build uses the directory
subsurface-mobile-build-arm(64), and when doing a docker android build
this directory is shared between host and container. That sharing is
good, as it nicely exposes the build tree to the host (for easy compare,
inspection, etc.). But reusing the same tree as the local one is
inconvenient (and possibly dangerous due to all kinds of caching
issues).

So, give the docker build its own output tree for the shared
subsurface-mobile-build-arm(64) build output.
