Subject: [PATCH] Added GRAPHVIZ_VERSION_COMMIT to autogen.sh

There are a few places in autogen.sh and configure.ac where a value
called GRAPHVIZ_VERSION_COMMIT is used. However this value was set to
unknown in autogen.sh. This commit solved this assigning the abbreviated
hash of last commit to this value.
