Zygo Blaxell ec9d4a1d15 crucible: fs: use a much smaller default search buffer size ...

It turns out we never use a value for m_buf_size that isn't the default,
and we also never ask for more than a few thousand items; however,
we do spend a ton of time memsetting the huge buffer to zero.

I don't know what the ideal size is, but 16K is a far better guess
than 1MB.  Let's reduce it for some immediate CPU benefit, and determine
what the size should be later.
