chore(android): allow to build FV app in docker container

Building the FirstVoices app is triggered in the top-level `build.sh`
if the two environment variables are set. Previously we didn't pass
these variables to Docker, so the FV app was never built even when the
env variables were set. This change passes the two variables to the
container, thus allowing to build the FW app in the docker container.
