[PATCH 06/26] admin: hoist out resolve_inboxes for -compact and -index

[Eric Wong <e@80x24.org>]

Both of these index-affecting commands should work similarly
on the command-line.

public-inbox-index no longer complains about unconfigured
~/.public-inbox/config; but often I found myself being
annoyed by that, anyways...
