Title: Make # of samples configurable, fix build on sunos

- Make # of samples configurable. Default # samples is 100M, and
wrk try to allocate 1.6GB memory block for statistics. This
could be a problem on small systems/VMs without enough RAM.
I made # of samples to be configurable via command line options
(-S). Default # of samples is also changed to 10M, now wrk uses
140MB for statistics which ls affordable for small-meory
environments.

- Fix build on sunos (SmartOS). SmartOS ioctl.h defines FIONREAD
only when BSD_COMP is defined, so I added it in Makefile.
