bitbake: bitbake: knotty: reduce keep-alive timeout from 5000s (83 minutes) to 10 minutes

The keep alive timeout is excessively long at 83 minutes (5000 seconds),
reduce this to 10 minutes: this should be long enough that it rarely
triggers in normal builds, but when it does it has useful information.
