xxhash packages update

[Jon Turney]

Doug,

What would you like me to do here:

- Apply this update and rebuild the package, and/or
- Process this like an ITA
- Something else?

Chad,

I think the filename xxhash.cygport is preferred, when the cygport 
itself sets VERSION and RELEASE

I needed to add SRC_DIR="xxHash-${VERSION}" to get this to build.

This seems to be fixed via a change to the patch, but applying the patch 
is (still) commented out in PATCH_URI?
