[PATCH] m68k: replace deprecated strncpy with strscpy

[Shankari02]

The use of strncpy() does not guarantee NUL-termination and is deprecated
in the Linux kernel. This code manually terminates the buffer afterward,
but using strscpy() is simpler and safer.

This change replaces the strncpy() + NUL termination pattern with strscpy().
