strip down to bare minimum, as filed in #92

[cs8898]

As in #92 already mentioned, this PR will Strip down the Image to the bare minimum.
Emulator images have to be downloaded separately.

The list is based on an image i use for Flutter development.

Thanks for the PR.
Wouldn't it be handy to have at least one image preinstalled, so that one can use the emulator without downloading an image?

[cs8898]

Would be handy, currently i never tested the emulator but during the current project i will test it.

Propably it would be handy to include also the x64 android 33 image (should be running more easily than arm emulation with qemu)

[mindrunner]

Yeah, I think for the normal image, we do not need to be super minimalistic. So we can add one of each kind!

Just found that Project
https://github.com/alvr/alpine-android

But i have not found any time to review/test the emulator inside of docker.
What would be the only reason to include the Images

[mindrunner]

I think ubuntu was never an issue with emulatort, but alpine is more tricky because of the whole libc thing

[mindrunner]

Decided to be a little bit less radical, see:

Would that be sufficient to you?
