tools/ci/docker/linux/Dockerfile: fix ccache when running container as user

Browse Source 
Normally ccache places the temporary files in `~/.ccache`, when invoking the container with
  `-u <uid>:<gid>`
as e.g. Jenkins does, this might result in a invalid/unknown home folder.
Thus ccache tries to write to `/.ccache` which doesn't exist and the user doesn't have any permissions.

Explicitly set `CCACHE_DIR` to a folder with appropriate permissions.
