Fix pgbench permute tests.

One of the tests for the pgbench permute() function added by
6b258e3d fails on some 32-bit platforms, due to variations in the
floating point computations in getrand(). The remaining tests give
sufficient coverage, so just remove the failing test.

Based on patch by Fabien Coelho.
