Subject: [PATCH] libredirect: Fix cross compilation `buildPackages`

Currently when cross compiling the `buildPackages.libredirect` has the wrong dynamic library extension.

To reproduce the issue run something like:

```
file $(nix-build -A pkgsCross.mingwW64.buildPackages.libredirect)/lib/libredirect.dll
/nix/store/80llmqa9lkabg3qnmglngzz22fwf739q-libredirect-0/lib/libredirect.dll: Mach-O 64-bit dynamically linked shared library x86_64
```

or

```
nix-diff $(nix-instantiate -A libredirect) $(nix-instantiate -A pkgsCross.mingwW64.buildPackages.libredirect)
```
