f_odlpluginbuild: Force .cacheid change

Recent builds use a stale cache of the ODL plugin artifact,
which leads to deploy failures (old Fuel plugin builder was used
to generate that artifact, which did not support multiple DEB
versions, silently excluding the default [5.0.0] version of ODL).

Chasing down the artifact across all build servers requires
extensive work, so we can just force a change in the cache id.

While at it, cleanup non-rebase plugin list (aesthetics).
