proton: Simplify find_nvidia_wine_dll_dir libdl discovery

Browse Source 
After testing DLSS+Proton on a different system than I normally use I
discovered that the call to `find_library("dl")` wasn't properly
discovering libdl.so.2

To simplify things here, just remove usage of find_library altogether.
