Subject: [PATCH] Avoid duplicate keyboard_map definition

the .h file is included in game.c, player.c and menu.c
With gcc15, the linker complains

/usr/lib64/gcc/x86_64-suse-linux/15/../../../../x86_64-suse-linux/bin/ld:
menu.o (symbol from plugin): in function `menu_setup_map':
 (.text+0x0): multiple definition of `keyboard_map'; game.o
(symbol from plugin):(.text+0x0): first defined here
