Martin Pitt 2e393a0c31 Add option for using a shared r/o results.cache
This is needed by the CI train, where we

  (1) don't want to cache intermediate results for PPA runs, as they might
      "accidentally" pass in between and fail again for the final silo,

  (2) want to seed britney with the Ubuntu results.cache, to detect regressions
      relative to Ubuntu.

Introduce ADT_SHARED_RESULTS_CACHE option which can point to a path to
results.cache. This will then not be updated by britney.
