commit git map: Fix --fetch-absent storing incorrect tree association

In order to not pollute builds, one should only store in the id
file the association between a commit and its *root* tree. As the
need for such a file only happens when asked to fetch absent
roots, which should be a quite rare use case, we can request the
whole tree of a commit to be served (incl. synced with remote
execution) and perform the subdir tree extraction locally instead.
