[PATCH] Benchtests: Add tests to cover longer string for strrchr

[Rajalakshmi Srinivasaraghavan]

While working on strrchr optimization for power8, found that the
existing benchtests is not enough to find the improvements
for longer strings.  Hence increasing the length to 512 to
measure the performance for a wide range.

	* benchtests/bench-strrchr.c (test_main): Increase the iteration
	to cover longer string.
