[PATCH] find-debuginfo: Pass -j down to dwz

[Kalev Lember <klember@redhat.com>]

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.
