doc: Use "dejavu sans" instead of "Helvetica" or "sans" in dot images.

Font-dejavu is (now) an input of fontconfig.  Specifying "dejavu sans" makes
generated images reproducible even when other fonts are installed (notably
font-google-noto).

* doc/images/bootstrap-graph.dot,
doc/images/bootstrap-packages.dot,
doc/images/coreutils-bag-graph.dot,
doc/images/coreutils-graph.dot,
doc/images/gcc-core-mesboot0-graph.dot,
doc/images/service-graph.dot,
doc/images/shepherd-graph.dot: Use fontname = "dejavu sans".
* doc/guix.texi (Full-Source Bootstrap): Update gcc-core-mesboot0.dot recipe
accordingly.
