[HL2MP] Fix inverted MIN/MAX punch angles for the AR2

[speedvoltage]

Issue: In pOwner->ViewPunch( QAngle( SharedRandomInt( "ar2pax", -8, -12 ), SharedRandomInt( "ar2pay", 1, 2 ), 0 ) );, it looks like the values were inverted for the AR2.

Fix: Set to pOwner->ViewPunch( QAngle( SharedRandomInt( "ar2pax", -12, -8 ), SharedRandomInt( "ar2pay", 1, 2 ), 0 ) );
