UserspaceEmulator: Don't assume entire malloc block is chunked
Accesses in the header (or trailing padding) of a malloc block should
not be associated with any mallocation since only the chunk-sized slots
actually get returned by malloc.
Basically, allow address-to-chunk lookup to fail, and handle such
failures gracefully at call sites.
Fixes #5706.
