benchmarks/gem_wsim: Perturb static_vcs selection across clients
Use the client id to alternate the static_vcs balancer (-b context)
across clients with the round robin flag (-R) - otherwise all clients
end up on vcs0 and do not match the context balancing employed by
media-driver.
v2: Put it behind the -R flag.
v3: Don't skip -R flag for -b context in scripts/media-bench.pl
