guf-recipe: Get rid of .version files

The required git-version.inc introduced .version files when used with
guf-recipe.inc. This results in layer changes when the source comes from
a in-tree sources.

There is no issue known to us, that the version files ever helped. Thus
keeping this "feature" seems pointless.

This also deactivates the SVN-like revision patching, that has the same
issue.
