docker: slim image, use rustup, build deps only on armv7 #352

A follow up to the reverted #342, with extra improvements:

Install rust from rustup. This seems to solve the issue reported in #342
Remove the cryptography==3.3.2 hack, latest version builds fine with a recent rust.
Install rust and other build dependencies only on arm/v7 (needed cause cryptography has no binary wheel).
Use the TARGETPLATFORM predefined arg.

I tested that it builds on all platforms, but only ran it on arm64 (not on arm/v7).

@chatziko: nice, it works!

Thanks a lot for the fix and your patient! :-)
