[N64 Bug] Bug in calculating kills for KillMaster medals

[jonaeru]

It was in the decomp comment and I found it interesting so I added the issue.
There is a bug in the calculation of the number of kills for KillMaster medals. Essentially, the number of suicides must be excluded.

alone, always excludes the number of player 2 killed
2 human, always excludes the number of player 3 killed
3 human, always excludes the number of player 4 killed
4 human, always excludes the number of first simulant killed

				for (j = 0; j < MAX_MPCHRS; j++) {
					// @bug: i should be k. The value of i was incremented after
					// the last iteration of its loop above so it'll be between
					// 1 and 4 inclusively depending on the number of players.
					// The bot nums start from 4 regardless of how many players
					// there are. So in a game with 4 humans, the kills on the
					// first bot will not be considered for the killmaster medal
					// which means the medal could go to a player who got fewer
					// total kills. Additionally, suicides are counted as kills
					// while the intention here was to omit them.
					if (i != j) {
						totalkills += mpchr->killcounts[j];
					}
