Similar adaptation of the deposit_check endpoint to allow reading remote tarballs when
using remote storage backends.

Refs. swh/infra/sysadm-environment#5129

Using the File api is consistent across various storage backends. The previous
implementation was only working for file storage. As we are migrating towards remote
backends, this no longer is enough.

Unfortunately though, we cannot rely on zipfile.is_zipfile or tarfile.is_tarfile as
those only works with local filepath. So we need to rely on testing & failing with
exception trapping to read properly the tarballs...

Refs. swh/infra/sysadm-environment#5129

They were only checking one tarball case (the ones reference in the ready_deposit_ok
deposit). This now creates as much deposit as there are extensions to check.

This only had to adapt the deposit so it's provided with a valid metadata. Otherwise,
the metadata checks were invalid, failing the overall tests.

Moreover, it was making some deposit tests failed when building packages
due to a side effect on the swh_storage fixture.

As for the webapp, ensure django 2.2 from backports is used on buster
as everything is already setup in puppet to have it in production.
