[IMP] runbot: use upgrade path

This commit will replace the symlink used for upgrade by the
upgrade-path.

The symlink was used before because old version does not support upgrade
path, but the decision was taken to now limit the testing to version
suporting upgrade paths in order to be able to support utils in another
repository latter.
