pgbench: Remove \setrandom.
You can now do the same thing via \set using the appropriate function,
either random(), random_gaussian(), or random_exponential(), depending
on the desired distribution. This is not backward-compatible, but per
discussion, it's worth it to avoid having the old syntax hang around
forever.
