Consider moving away of busybox

[tlaurion]

Some alternatives that might be a direct replacement:

• rustybox (as name implies its in rust)
• toybox (c more posix compliant)

Opening this issue because lack of wget/curl in https with cert verification is a still a problem if we want to be able to outsource some of the things currently packed in the evergrowing initrd under Heads

Note: haven't compared applets provided yet, while toybox from my limited experience under Android shell seems to be good enough.

We would have to pack all features in and see what breaks and go from there.

Here is PoC code (not functional) that I tried to create with my limited knowledge of python. Anyone that could make it functional would give us a clear view of what is there and what is missing to make a better decision for the project

@tasket, thinking of you but do not feel obligated in any way! @JonathonHall-Purism as usual, tagging you since that could be of a really good help going forward
