Disable spinlocks

Now that c++11 branch has been merged in master,
disable unconditionally the spinlocks and use mutex
instead. This will allow to run fishtest even on HT
machines withouth changes.

In the future we will reintorduce spinlocks, once
we will have took care of fishtest.

No functional change.
