Revert ".travis.yml: Cache Avocado cache"

This reverts commit c1073e44b46490133e16420e1784dec7bcd4e030.

The Avocado tests have been removed from Travis a long time ago with
commit c5008c76ee ("gitlab: add acceptance testing to system builds"),
so we don't need to cache the avocado files here anymore.
