Initialize archivers as soon as possible when running git-archive. Various non-obvious behavior depends on having the archivers initialized, such as determining the desired archival format from the provided filename. Since 08716b3c11 ("archive: refactor file extension format-guessing", 2011-06-21), archive_format_from_filename() has used the registered archivers to match filenames (provided via --output) to archival formats. However, when git-archive is executed with --remote, format detection happens before the archivers have been registered. This causes archives from remotes to always be generated as TAR files, regardless of the actual filename (unless an explicit --format is provided). This patch fixes that behavior; archival format is determined properly from the output filename, even when --remote is used.
