Fix another wstring Boost filesystem linking error

I couldn't get the LL_WARNS to link on Windows yet, so they're just
disabled for now, they're only warnings to the users anyway.

The error was:

llfilesystem.lib(lldiskcache.obj) : error LNK2019: unresolved external symbol "__declspec(dllimport) void __cdecl boost::filesystem::detail::path_traits::convert(unsigned short const *,unsigned short const *,class std::basic_string<char,struct std::char_traits<char>,cla
