Use fuzzy comparison for another Flickable StopAtBounds case.
Use fuzzy comparison for another Flickable StopAtBounds case.

Be consistent with 268f4615dcf19aad3603833af83ba28eca886aa5, and use
fuzzyLessThanOrEqualTo when checking whether we are at or past the bounds
when dragging. This prevents a condition where:

1. A Flickable with StopAtBounds is at one of the bounds.
2. A quick flick will sometimes (rarely) cause the Flickable to flick
   past the bounds.
