patch 8.1.1344: Coverity complains about possibly using a NULL pointer

Problem:    Coverity complains about possibly using a NULL pointer and copying
            a string into a fixed size buffer.
Solution:   Check for NULL, even though it should not happen.  Use
            vim_strncpy() instead of strcpy().
