Upgrade to sysbox 0.7.0

[maxpschonder]

I faced issues related to nestybox/sysbox#973 and upgraded sysbox to 0.7.0 with some additional fixes and improvements for the workflows.

Thanks for your contribution @maxpschonder! It might be no harm to hold off a little while until sysbox v0.7.0 is actually fully released (at the time of writing, it's not showing up for me as the latest release).

Might be related: nestybox/sysbox#996

For some reason, as of writing, there is a tag for the release, but there are no binary releases associated with it: https://github.com/nestybox/sysbox/releases/tag/v0.7.0

Can you update the amd64 SHA in Makefile as well?

I can't push to your branch but here's the diff that allows the build to succeed:
