workers_bindid is either set explicitly in the conf passed to
starpu_init(), or filled from the STARPU_WORKERS_CPUID environment
variable, i.e. it is only what was requested, while workers[i].bindid
is what is actually used during execution, which might differ if a GPU
worker got bound to one of them for instance.
