Run filebench with addr_no_randomize

Filebench causes segmentation fault on system when ASLR is enabled as memory starts to overlap when many processes are defined with same binary of filebench. So running benchmark with addr_no_randomize personality making the benchmark to run cleanly. Signed-off-by: Ayush Jain <[email protected]>
