(WiiU) libmocha: Add LaunchHomebrewWrapperEx

Required library call to pass arguments between different homebrew apps, which
is something that RetroArch needs to pass the content path to cores.

I'll try and get this upstreamed once <sysapp/args.h> is in a released version
of wut, but for now we'll just have to carry it in-tree.
