PreviewSubmit: always allow tgz format

Browse Source 
Currently the setting archive.download is used in two different cases:
* It is used to specify formats for downloading a patch set archive
* It is used to specify the formats in preview_submit

However these two use cases serve different purposes:
The format for downloading a patch set archive can be used to
adapt to the resource environment:
* When bandwidth is cheap, tar is a good choice.
* When CPU is available, tbz2 and txz are good candidates.
* tgz does an ok job w.r.t. any resource.
* the admin may deem downloading patches as an archive is
  not a good idea and disable it completely by allowing no formats.

The format for preview_submit is different, though, because it is
used as a wrapper around already compressed files (git bundles),
so it makes no sense to spent a lot of CPU to compress it further.
Also at least one format needs to be allowed, otherwise this call
cannot be used. Always allow tgz as that format is a good trade off
for all resources.

You need to give a parameter '?format=zip' or '?format=tar' to specify the
format for the outer container.
format for the outer container. It is always possible to use tgz, even if
tgz is not in the list of allowed archive formats.
To make good use of this call, you would roughly need code as found at:
