Added missing Mega Man 5 INI file

While going through and testing various NES VC games, I noticed Mega Man
5 was just displaying a black screen but the sound and button inputs
were working as expected. Turns out, there is no INI file for that game
id. Copying and renaming Mega Man 4's INI file appears to be enough to
get the game going.
