[PATCH 8/8] lei rm: move generic input_maildir_cb to LeiInput parent class

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

It's not much of a savings, right now, but maybe it can be in the
future.  I wanted to eliminate the "lei convert" one, too, but
convert needs to preserve keywords which isn't possible with the
generic fallback, so new tests were written for convert, instead.
