Another option is to use something close what the builtin env
DEBUGINFOD_PROGRESS=1 code does: print self-overwriting messages with
\r rather than \n.  That way many messages can come, but they don't
overpower the screen.  Really, the main reason I put in this
progressfn into debuginfod-find was to help test that API within the
testsuite.  Maybe now, we don't need that option to do anything but
set the env var, therby using the common code.
