selftests: Move two functions from mlxsw's qos_lib to lib
The function humanize() is used for converting value in bits/s to a
human-friendly approximate value in Kbps, Mbps or Gbps. There is nothing
hardware-specific in that, so move the function to lib.sh.
Similarly for the rate() function, which just does a bit of math to
calculate a rate, given two counter values and a time interval.
