stream: don't set sector size on cache

This is useless on the cache side. The sector is needed only to deal
with stream implementations which are not byte addressable, and the
cache is always byte addressable.

Also set a default read_chunk value. (This value is never used unless
you chain multiple caches, but it's cleaner.)
