This reverts back to using `git archive` for the source archives... but
will keep supporting extra files.
##### How it works:
Basically, we run `git archive` as before.
Then, we make a backup of the generated archive, and create a new one
copying by reading from the backup and writing into the new one.
Finally, we write the extra files to the new one as well.
This only happens if the configuration does have extra files, otherwise,
just the simple `git archive` will be run.
PS: we can't just append to the archive because weird tar format
paddings et al.

alternative to #3806
the idea is that both `context.New` and `context.Context{}` are never
used in tests.
not sure yet how much I like it, so far code does look a bit more
readable though.
