0xBenchmark: Stop using fork() in native benchmarks.

The barrier function locks up when used in conjunction with multiple
processes. The "P" option uses fork() to launch mulitple parallel
operations.

This change will use "T" (threads) instead of "P" (processes) when
applicable, and also exclude the fork. exec and exit benchmark steps.
