Execution API: support cwd

... following the remote-execution standard that all output paths (but
none of the input paths) are relative to the working directory.
Therefore, the executor has to do the path translation. For our
implementation of the API interface
- the local API now handles cwd correctly,
- the remote API forwards cwd correctly, and
- the git API continues to report actions as not implemented.
