rpm: add back find-debuginfo support

RPM upstream removed find-debuginfo and switched to use debugedit
since the following commit.

  04b0805a75

According to https://github.com/rpm-software-management/rpm/blob/master/INSTALL,
debugedit is needed by rpm. More specifically it's needed by rpmbuild
to supporting generating debuginfo package when %debug_package is enabled.
