Title: graphviz: add universal option

Graphviz can build universally if it is built with a universal
pcre, swig, and gettext. Add a `--universal` option. Change
to using sha1. Leave the `fails_with` build version alone because
Graphviz builds on Mountain Lion with clang-4.0.

Tested on ML with clang and llvm from XCode-4.4.

Fixes #13827
