On init odp creates odp_sched_pool. We can not modify API to add new
parameter to odp_pool_param_t and this pool should not be shared
between different processes. To do that implemented internal linux-generic
function with parameters to created shm.
Note: create shm before and then provide it to the pool does not work
because shm argument likely will be dropped from odp_pool_create() (patch
already posted.).
