load_dll: iterate over all folders in path, POC

this patch allows load_dll to iterate over every folder in the given path and
check for a matching dll until one could be loaded. As soon as a dll is found
and could be loaded it returns, introducing zero overhead for the most
applications. Only on WoW it might try multiple dlls until a matching one is
found.
With this patch Planetside 2 x64 doesn't complain about missing xinput1_3 any
more.
