Cygwin: cygthread: stop running all cygthreads at HIGHEST priority.
Given the number of scenarios we're using cygthreads, it just doesn't
make sense to run all of them with HIGHEST priority in preemptive
obedience.
Drop setting the cygthread priority and let the cygthreads decide
by themselves. For the time being, run all cygthreads with normal
priority. Change this locally in the thread function, if required.
