Files update

I'm not sure of the status for possibly maintaining 'Files' via
automation, so manually add the new file 'gitinfo.sh' to sys/unix.
There was a sys/unix/hints file that wasn't listed, so add linux-qt4.
The whole win/Qt4 subdirectory is missing though.  I don't even
remember that being added.
