Fix a few things that upset rpmlint (which then failed the build).

file.c: In function 'int swi_osfile(int, const char*, char*, char*)':
file.c:350:1: warning: control reaches end of non-void function [-Wreturn-type]
keyboard.c: In function 'int swi_joystick_read(int, int*, int*)':
keyboard.c:92:1: warning: no return statement in function returning non-void [-Wreturn-type]
sound.c: In function 'int swi_sound_speaker(int)':
sound.c:397:1: warning: no return statement in function returning non-void [-Wreturn-type]
