Use Sys_LoadDll to search in the local directory for the fallback default
renderer.

When using USE_RENDERER_DLOPEN and specifying an unloadable cl_renderer cvar,
the fallback opengl1 renderer fails to open. It seems it uses Sys_LoadLibrary
instead of Sys_LoadDll. The former checks the PATH only, whereas the later
checks the PATH and/or the current directory. Thus, it seems after talking to
Thilo on the IRC channel, that it should be using Sys_LoadDll instead, which is
what the attached patch does.
