md5deep: Add recipe for md5deep package version 4.4

I need to build hashdeep/md5deep within OE to include it in my images. This recipe enables OE to cross-compile md5deep. I needed to add the patch as do_configure_qa is complaining about cross-compilation errors otherwise. I added a pull request for the issue with the variable expansion to hashdeep as well.
