jenkins: Don't bind for CI tests

The CI tests on the AWS jenkins instance all run on instances with
1 core.  There's a special case in OMPI to bind to core for a 2
process run for benchmarking reasons, and this was causing failures
in mapping because there aren't 2 cores on the instance.  So instead
turn off binding for these small tests.
