The reftable blocksource provides a generic interface to read blocks via different sources, e.g. from disk or from memory. One of the block sources is the malloc block source, which can in theory read data from memory. We nowadays also have a strbuf block source though, which provides essentially the same functionality with better ergonomics. Adapt the only remaining user of the malloc block source in our tests to use the strbuf block source, instead, and remove the now-unused malloc block source.
