Multiplayer buy menu does not fit on screen with 16:9 resolutions

[Kingo64]

Describe the bug
The buy menu in multiplayer does not fit on screen in 16:9 resolutions and potentially 21:9 resolutions. This does not appear to be an issue with older versions such as the December 2020 Preview release or vanilla. It is only present in newer versions of OpenXRay and the current master.

To Reproduce
Steps to reproduce the behavior:

1. Start a multiplayer session
2. Join a team
3. Press B to open the buy menu

Expected behavior
I would expect the buy menu to correctly fill the screen and have the buttons on the right able to be pressed instead of being cut off.

@yohjimane Just wanted to ping you on this in case you have come across this or have already fixed it as I know you have a couple open PRs related to multiplayer support. Figured you may have good insights.
