Add entries for . and .. in MntPoints::IterateDirectory (#3414)

Browse Source 
Grand Theft Auto V uses sceKernelGetdents in a loop to search through the contents of /download0, but will always check the first returned directory entry regardless of what value the function returns.
As it turns out, this will never fail on real hardware because all directories have entries for . and .., while the game code throws an exception on shadPS4 because we don't emulate these entries.
