Minor git-archive bug

Minor git-archive bug

[Jeff Garzik]

"git-archive --list" requires a git repository.  Certainly listing the 
archive formats doesn't /really/ require such things.

[PATCH] Revert "builtin-archive: use RUN_SETUP"

[René Scharfe]

Commit 64edf4b2 cleaned up the initialization of git-archive,
at the cost of 'git-archive --list' now requiring a git repo.
This patch reverts the cleanup and documents the requirement
for this particular dirtyness in a test.
