glx: Fix error message when no driverName is available
Just provide a "(null)" literal in case driverName is NULL.
In file included from ../src/glx/dri3_glx.c:76:
../src/glx/dri3_glx.c: In function ‘dri3_create_screen’:
../src/glx/dri_common.h:70:36: error: ‘%s’ directive argument is null [-Werror=format-overflow=]
70 | #define CriticalErrorMessageF(...) dri_message(_LOADER_FATAL, __VA_ARGS__)
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
../src/glx/dri3_glx.c:1002:4: note: in expansion of macro ‘CriticalErrorMessageF’
1002 | CriticalErrorMessageF("failed to load driver: %s\n", driverName);
| ^~~~~~~~~~~~~~~~~~~~~
../src/glx/dri3_glx.c:1002:50: note: format string is defined here
1002 | CriticalErrorMessageF("failed to load driver: %s\n", driverName);
| ^~
