Subject: [PATCH] pock: Set the sieve vector size correctly.

Having calculated `sievesz' so carefully, it seems a shame not to use it
-- especially when that results in the sieve vector being thirty times
larger than it should be.

More seriously, this causes the `smallprimes' iterator to continue way
past its proper end-point.  Fortunately, all of the uses in this program
are safe.
