gnu: wine: Update to 6.20.

This patch updates the logic by which the “so_dir” is patched onto RPATH.
Unlike the old hack, this one affects all Unix libraries, so it might be a tad
bit overkill, but better be safe than sorry when it comes to stuff that'd
break in validate-runpaths.

* gnu/packages/wine.scm (wine): Update to 6.20.
[#:phases]: Replace ‘patch-makefile’ with ‘patch-makedep’.
(wine64): Likewise.
