admin: resolve inboxes to absolute paths for index

Some of my ancient v1-only scripts called public-inbox-index
to operate on GIT_DIR:

	GIT_DIR=/path/to/foo.git public-inbox-index

This change ensures they keep working, otherwise "." will be
passed to the --git-dir= switch of git(1) because that's the
default directory if no inboxes are specified on the
command-line.

Fixes: 9fcce78e40b0a7c6 ("script/public-inbox-*: favor caller-provided pathnames")
