Include count for \0 character when using strncpy to implement strdup.

We have to include the \0 character in the length when copying a
string with strncpy() for which length was found with strlen().
Otherwise the destination will not get null terminated - except that
we explicitly zeroed it out earlier.

This quiets down the compiler's warnings.
