rcu: Update TREE05.boot to test normal synchronize_rcu() 



Add extra parameters for rcutorture module. One is the "nfakewriters"
which is set -1. There will be created number of test-kthreads which
correspond to number of CPUs in a test system. Those threads randomly
invoke synchronize_rcu() call.

Apart of that "rcu_normal" is set to 1, because it is specifically for
a normal synchronize_rcu() testing, also a newly added parameter which
is "rcu_normal_wake_from_gp" is set to 1 also. That prevents interaction
with other callbacks in a system.
