backports: devel/backports-update-manager: fix for older shutil.move

Older shutil.move does not seem to like it when there are
symlinks on a target, to account for this and to make things
clearer just split up the work on the lib/modules and usr/src
directory.

This fixes running devel/backports-update-manager on OpenSUSE 13.1
base install.
