[PATCH] Add --dwz-single-file-mode argument for find-debuginfo.sh.

["Martin Liška" <mliska@suse.cz>]

Sometime it's handy to disable multi-file mode and the patch
adds option for that: --dwz-single-file-mode.

It will be used in openSUSE for packages that use baselibs.conf
mechanism.

The patch was already approved in rpm pull request:
https://github.com/rpm-software-management/rpm/pull/1579
