Build an arvados/jobs Docker image from local git tree.

Intended for use by developers working on arvados-python-client or
arvados-cwl-runner and need to run a crunch job with a custom package
version.  Also supports building custom cwltool if CWLTOOL is set.

Syntax:
        WORKSPACE=/path/to/arvados $(basename $0)

WORKSPACE=path         Path to the Arvados source tree to build packages from
CWLTOOL=path           (optional) Path to cwltool git repository.
