Fix "git cl map-branches -vvv"

CL https://codereview.chromium.org/1172223002 changed the meaning of the
third value in the tuple returned by get_cl_statuses from a color to the
status of the branch and broke the formatting of output.

Convert the status to the color using color_for_status helper function.
