workaround for broken matchmaking/online functionality in various games

Online functionality in several games was broken by:

Notably Battlefield 4 cannot join matches, MK11 cannot go online, NBA2k21
cannot join online matches or see friends, Rocket League cannot join
matches/see friends, steam cannot connect online.

This was partially fixed upstream (not sure what commit), however Battlefield 4
matchmaking still remains broken. The attached patch (from Zebediah Figura)
resolves the BF4 and other relevant game issue. Opening bug for further
investigation.
