xkbcomp/keymap: correct ACTION_MODS_LOOKUP_MODS handling The xkblib spec says: If XkbSA_UseModMapMods is not set in the flags field, the mask, real_mods, vmods1, and vmods2 fields are used to determine the action modifiers. Otherwise they are ignored and the modifiers bound to the key (client map->modmap[keycode]) are used instead. So we should just assign the modmap without considering what's there.
