Enhancement: for mloginfo --queries round mean (ms) and 95%-ile (ms) to integers

[niccottrell]

It seems that we don't need all this precision for means since at least for the top queries, we probably have a large count and quite a bit of variance. The simplicity and readability of rounding to a whole integer should outweigh any benefits of the precision.
