largefiles: drop setting lfstatus in overridelog (issue4334)
lfstatus should only be True for operations where we want standins to be
printed out. We explicitly do not want that for historical operations like log.
Other historical operations like hg diff -r A -r B don't print out standins
either.
This is required to fix issue4334, but doesn't fix anything by itself. That's
why there aren't any tests accompanying this patch.
