runqueue: Sanity check BB_NUMBER_THREADS
Bitbake does really weird things with negative or zero numbers of threads
which is confusing to the user. Add a sanity check for this.
When you have code doing arithmetic on the values and a VM reconfigures
to only a single thread, negative numbers are easier than you'd think.
