Subject: gnu: wine: Hard-code vulkan loader.

* gnu/packages/wine.scm (wine)[arguments]: Add 'wrap-executable phase.
* gnu/packages/wine.scm (wine64)[arguments]: Add 'wrap-executable
phase. Copy the real wine-preloader instead of the wrapped version.
* gnu/packages/wine.scm (wine-minimal)[arguments]: Don't inherit phases. Add
'patch-dlopen-paths phase.
