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.
