[PATCH] ui_repolist: get modtime from packed-refs as fallback

[mailings at hupie.com (Ferry Huberts)]

From: Ferry Huberts <ferry.huberts at pelagic.nl>

When no modtime could be determined then as a final
fallback try to get it from the packed-refs.

This will show an idle time when a repository has been packed
with all refs in the packed-refs.
