Re-port dump_bitset_clear to -fsanitize=undefined

* src/pdumper.c (dump_bitset_clear): Skip the memset if the
size is zero, because in that case the destination might be NULL.
This fixes a bug introduced in 2019-07-26T06:17:52Zeggert@cs.ucla.edu.
Add a comment to make the bug less likely to reoccur.
