Correctly handle a checksummed file that depends on a non-checksummed file.

Browse source 
We were rebuilding the checksummed file every time because redo-ifchange was
incorrectly assuming that a child's changed_runid that's greater than my
changed_runid means I'm dirty.  But if my checked_runid is >= the child's
checked_runid, then I'm clean, because my checksum didn't change.

Clear as mud?
