android/docker: combine CMD invocations into a single line (#448)

android/docker: combine CMD into a single line

 updates tailscale/corp#21644

docker ignores all but the last CMD invocation.  These
have to be combined into a single line.  The clean is
redundant.  We run a clean on the mounted directory
before we kick off make docker-run-build.
