    find-debuginfo: Pass -j down to dwz
    
    Now that dwz 0.15 supports parallel jobs, add a way to control it from
    here. find-debuginfo already has a -j parameter so we can just extend it
    and pass the value down to dwz as well.
    
    This should fix building large packages on memory constrained builders,
    such as webkitgtk on s390x in Fedora koji build system, where we can now
    use the -j option to tune down parallelism to avoid running out of
    memory during dwz run.
    
    Add a configure check to make sure the installed dwz supports the
    -j option.

I will, but as you might have seen the rawhide buildbot just failed.
All others seem green, so it probably is the new gcc or some compiler
flag changes in fedora rawhide:
https://builder.sourceware.org/buildbot/#/changes/17730

As soon as I figure out how to get the testsuite green on rawhide I'll
also push this patch there.
