New Ryujinx needs an higher value of vm.max_map_count
Browse files Browse the repository at this point in the history 
Since this Ryujunx PR [1] ot returns a warning if vm.max_map_count < 524288,
so just set an higher value.

To be coherent with what other Linux distrubitions are doing, use
2147483642.

This is the value used by Batocera 37 itself [2], SteamDeck and Fedora 39 [3].

There is not need to re-set the value each time yuzu or Ryujinx is
started, so just set it once on startup.
