Update trace.sh for Pin 2.14 and recent Linux kernels
Update trace.sh for Pin 2.14 and recent Linux kernels

This old Pin will normally refuse to run with kernels past 4.10 or so,
but it seems in my initial invesigation to be OK on 4.15 if you give it
the -ifeellucky option to ignore the check. I think updating to Pin 3.x
would be hard because of other restrictions.
