[bug#67675] [PATCH] gnu: dante: Enable preloading support.

[guix-patches--- via]

Dante uses dlopen which doesn't work with libc.so but libc.so.6.
This fixes socksify, which is patched to skip invoking uname needlessly.

* gnu/packages/networking.scm (dante): Enable preloading support.
* gnu/packages/patches/dante-non-darwin.patch: New file.
