prog: restricts hints to at most 10 attempts per single kernel PC

We are getting too many generated candidates, the fuzzer may not keep up
with them at all (hints jobs keep growing infinitely). If a hint indeed came
from the input w/o transformation, then we should guess it on the first
attempt (or at least after few attempts). If it did not come from the input,
or came with a non-trivial transformation, then any number of attempts won't
help. So limit the total number of attempts (until the next restart).
