ofmt: get rid of the debuginfo parameter to ofmt->cleanup()

Get rid of the completely pointless "debuginfo" parameter to
ofmt->cleanup().  Most backends completely ignore it, and the two that
care (obj, ieee) can simply test dfmt instead.

Also, dfmt is never NULL, so any test for a NULL dfmt is bogus.
