server: Extend display name string size
Typically this is a number between 0 and 32. Just that the compiler doesn't
know that well. Make the string buffer a bit larger, so that it fits the
longer integers. Fixes build warnings like:
../subprojects/wayland/src/wayland-server.c: In function ‘wl_display_add_socket_auto’:
../subprojects/wayland/src/wayland-server.c:1649:70: error: ‘%d’ directive output may be truncated writing between 1 and 11 bytes into a region of size 8 [-Werror=format-truncation=]
1649 | snprintf(display_name, sizeof display_name, "wayland-%d", displayno);
| ^~
../subprojects/wayland/src/wayland-server.c:1649:61: note: directive argument in the range [-2147483647, 32]
1649 | snprintf(display_name, sizeof display_name, "wayland-%d", displayno);
| ^~~~~~~~~~~~
../subprojects/wayland/src/wayland-server.c:1649:17: note: ‘snprintf’ output between 10 and 20 bytes into a destination of size 16
1649 | snprintf(display_name, sizeof display_name, "wayland-%d", displayno);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
