Rename find-package to solve misconflict with rpm

It is not that easy to ship find-package as part of rpm-build.
We have to drop find-package from the filelist of rpm as well. For this
change to enter Sisyphus, both rpm-build and rpm have to be changed and
rebuilt in their own base build chroots.

If rpm-build is built to include find-package first, rpm is
uninstallable in the base chroot due to a misconflict, so it cannot be
rebuilt.
If rpm is built to exclude find-package first, it disappears from the
base chroot altogether, making rpm-build break, so no
package can be built as well.
