varnish: fix jemalloc chunk size config option name
The option to tune virtual memory chunk size is lg_chunk, not
lg_chunk_size. The values we have been using so far have thus been
ignored, and the default value for lg_chunk (2^22=4M) has been used.
Set the chunk size to 512K (2^19) on cache_text, and 1M (2^20) on the
others. We can re-experiment with lower values later on.
Bug: T135384
