Requires X11 on linux

[exalented]

The TRX 4.6 linux release requires X11.

Without env SDL_VIDEODRIVER=x11 ./TR1X (or unsetting it from wayland) I get:

$ ./TR1X
specific/s_shell.c 266 main Game directory: /TR/
specific/s_shell.c 169 S_Shell_ShowFatalError Cannot initialize SDL: wayland not available

$ env SDL_VIDEODRIVER=x11 ./TR1X
specific/s_shell.c 266 main Game directory: /TR/
libtrx/game/input/backends/controller.c 378 M_FindController 0 controllers
specific/s_shell.c 372 S_Shell_CreateWindow Trying GL backend 3.3
..
libtrx/gfx/context.c 136 GFX_Context_Attach OpenGL renderer string: Mesa Intel(R) Arc(tm) A750 Graphics (DG2)
..
game boots fine..

It would be nice to not need x11 moving forward.
I believe the ubuntu:latest image needs wayland.
