Fixed Magyar starting troops in 867

Since patch 2.2, it has been literally impossible for the Magyars to win against Bulgaria in the 867 start.

This patch addresses that.  Sometimes they win, sometimes they lose.  They've won 2 out of 3 observation trials since I made this change.

They are still relatively weaker and have a very hard (but achievable) road ahead trying to survive in the Carpathian Basin.
