Dave Chinner e714acc0ef reduce the number of processes forked
One of the big cpu time consumers when running xfsqa on UML
is forking of new processes. when looping lots of times,
using 'expr' to calculate the loop counter increment means
we fork at least once every loop. using shell builtins means
that we don't fork and many tests run substantially faster.

Some tests are even runnable with this modification. e.g. 110
went from taking 4500s to run down to 9s with the loop iterators
changed to avoid forking.
