Add android.adb_args option

[germn]

Now, if a buildozer is in a Docker container, to make it work with a Linux host you have to pass several unobvious flags to the Docker. I wasn't able to make it work with Windows host at all.

However, it's possible to achieve the same much easier, if we could pass a flag to the adb command. It makes buildozer in a Docker work without any additional Docker flags and on any host (AFAIK).

The PR adds a possibility to pass an argument(s) to the adb. Uncomment the default value (-H host.docker.internal) and run buildozer android deploy from inside Docker to see the effect.

I would love to see this PR merged. I was just struggling with the problem of deploying to an android device from inside a VS Code devcontainer based on the official kivy/buildozer container. With this PR I can configure buildozer in the devcontainer to use the host's adb server which has already been configured with my devices. This enables seamless build, deploy, and logcat viewing from within the devcontainer.

Let's try to ping few people who can merge: @inclement @AndreMiras @tito

Note, however, that instead of waiting you can create your fork of buildozer, merge the PR and use it now.
Or you can, for example, install buildozer from the PR's branch:
pip install https://github.com/germn/buildozer/archive/add_adb_args_option.zip
