Fix some entities in general.ent for releases

Two entities downloads-root-systemd and patch-root were not
modified when switching to release:
- change the name of downloads-root-systemd to downloads-root since
the aim is to not have "-systemd" entities, and use "&blfs-version;"
for it
- create a patch-version entity (this one does not change for
systemd), and use it in patch-root
