services: guix-build-coordinator: Support extra environment vars.

Browse source 
I'm looking at this because I need to do some debugging of Guile's GC, and
there are some useful environment variables for that, but it should be
generally useful.

* gnu/services/guix.scm (guix-build-coordinator-configuration-extra-environment-variables):
New procedure.
(guix-build-coordinator-shepherd-services): Pass the environment variables to
the shepherd.
* doc/guix.texi (Guix Services): Document it.
