ui-snapshot: pass -n to gzip, to suppress timestamp
Since cgit snapshots of tags are often used for releases, we don't want the rarely used feature of the gzip compressor that includes an embedded timestamp into the archive, since this makes each tarball of the same (potentially signed) tag different. This commit refactors the archive handling code a bit so that each different format is able to run with an arbitrary argv for the filter.
