m68k: Replace memcpy() + manual NUL-termination with strscpy() 



Use strscpy() to safely copy the command-line string instead of memcpy()
followed by a manual NUL-termination.

The source string is also NUL-terminated and meets the __must_be_cstr()
requirement of strscpy().

No functional changes intended.
