use slave for row estimate in updateCollation.php

jcrespo reported a lag spike at the very beginning of running this
script. I'm guessing that's due to counting how many rows in
categorylinks to give the progress bar. Since we only need a
rough estimate for the progress meter, make that query run on
a slave. Also add a wfWaitForSlaves() immediately after it for
good measure.
