Message: WT-2631 nullptr is passed for parameters marked with attribute non-null (#2955)

WiredTiger sometimes calls __wt_buf_set() to clear WT_ITEM structures,
in which case memmove is called with a NULL pointer (and a length of 0).
The Debian 8 clang undefined behavior sanitizer validates that memmove
is not passed a NULL pointer, don't call memmove if the length is 0.
