The nightly builds seem to often trip over each other when
uploading the source tarball from ubuntu20.
Restrict it to being built only on the appimage build (ubuntu16).
The mac builds started to fail with a crate resolution issue that I
can't reproduce locally shortly after I updated the cache action. Let's
tweak the cache key to see if that clears things up.
This is untested beyond eyeballing the locally generated file.
Will need to make a couple of tags to test this for sure.
