gdrom: use strscpy in probe_gdrom_{setupcd,setupdisk}

strcpy() has been deprecated¹ because it performs no bounds checking on the destination buffer, which can lead to buffer overflows.

While the current code works correctly, replace strcpy() with the safer strscpy() to follow secure coding best practices.

Compile-tested only. Adding arch/sh/ maintainers since that's the only platform where this driver can be used.
