m68k: emu: Mark version[] __maybe_unused

When building with W=1:

    arch/m68k/emu/nfeth.c:42:19: warning: ‘version’ defined but not used [-Wunused-const-variable=]
       42 | static const char version[] =
	  |                   ^~~~~~~

Fix this while obeying the wishes of the original copyright holders by
marking version[] with __maybe_unused.
