Build failed on msys2 windows

I found the build error during the installation of telescope-fzf-native on MSYS2 UCRT Windows.

Nvim version

NVIM v0.9.5 Build type: Release LuaJIT 2.1.1710088188

This issue is the same as #101, but I would like to introduce the different workaround.

 else

The environment variable MSYSTEM can be set to one of the followings:

MSYS, UCRT64, CLANG64, CLANGARM64, CLANG32, MINGW64, MINGW32

The build is successful other than CLANGARM64. Although I couldn’t verify it in the CLANGARM64 environment, I believe this patch is fine.

Thank you,
