sstate: additional debugging when fetch fails occur

Autobuilder has been showing things like:
Checking sstate mirror object availability...ERROR: SState: cannot test file://universal/d9/bc/sstate:xz-native:x86_64-linux:5.2.5:r0:x86_64:8:d9bced04b194d5fc8d778eb8a0d674fa7375a42c8c50a9237e6d7672e9e7a00c_deploy_source_date_epoch.tar.zst: TimeoutError('timed out')

done.

which is not helpful. To find out what really happened and where, the original
traceback is needed too.
