Use relative cache paths

André Anjos requested to merge fix-caches into master

This MR makes all cache paths relative to ${CI_PROJECT_DIR} - using full paths does not seem to cut it:

WARNING: /Users/gitlab/builds/sAZPGTqW/0/bob/expose/.cache/pre-commit: no matching files. Ensure that the artifact path is relative to the working directory
