This returns something like "N-73264-gb54ac84". This is much more useful
than the individual library versions, of which there are too much and
which are very hard to map back to releases or git commits.

This actually just returns the contents of the already semi-public
av_util_ffversion variable. But this variable is undocumented, has no
public declaration, requires accessing variables over library
boundaries (which is apparently frowned upon and/or causes various
issues), and lacks av_export.
