bitbake/runqueue: Drop check_stamps function, it is obsolete and unused 

This was originally used to check the consistency of the stamps in one function
call. This turns out to be inefficient, unnecessary and if it were necessary,
check_stamp_task() could be called in a loop. The function has been unmodified
for a while and likely contains bugs. Its best simply removed.

(Bitbake rev: 728ffde1bd69b880d48fe8523b1616956d13616e)
