Patch to make the game even launch on Ryzen CPUs.

As you can see on https://wildfiregames.com/forum/index.php?/topic/28367-amd-ryzen-threadripper-user-read-before-posting/, games-strategy/0ad-0.0.23b_alpha can't run on Ryzen and Threadripper CPUs without some patches, which can be found on https://code.wildfiregames.com/file/data/6kx26sfefazlyr4rt2y7/PHID-FILE-4ay3h6ssd7mou2cmp37b/D2353.diff and https://code.wildfiregames.com/file/data/hsogdbcylbgln4pej67f/PHID-FILE-w6lbby5m5ndjv5nqaz4y/D2726.diff (this one is rather large and has a lot of changes that only affect Windows builds; for Linux, only those made to the timer.cpp file are important, according to a dev).

However, the file paths on those patches must be adjusted in order to work on Portage. I'm sending attached two .diff files that I inserted in /etc/portage/games-strategy/0ad to make it run on my 3700X CPU.

As such, you could add a new USE flag for Ryzen CPUs to get these patches implemented on the systems that could use it.
