hw: get a thread cap in Thread_base constructor

Browse Source 
Previously this was not done before Thread_base::start(..) in
base-hw as it was not needed to have a valid cap that early. However,
when changing the affinity of a thread we need the cap to be valid
before Thread_base::start(..).

fix #1151
