More accurate 'go nodes' searches at low count

Makes the actual number of nodes searched match closely
the number of nodes requested, by increasing the frequency
of checking the number of nodes searched at low node count.
All other searches retain the default checking frequency of
once per 4096 nodes, and are thus unaffected.

Passed STC as non-regression
LLR: 2.95 (-2.94,2.94) [-3.00,1.00]
Total: 26643 W: 4766 L: 4655 D: 17222

No functional change.
