syz-fuzzer: don't sleep after transient executor errors
There is non-0 rate of transient executor errors.
Currently we do full GC, free OS memory and sleep for a second after then.
This was more meaningful when the fuzzer was in the VM as the fuzzer process
consumed lots of memory. Now it consumes only ~20MB, any OOMs are likely
not due to the fuzzer process.
So instead sleep briefly and only after several retries
(I would assume most errors are fixed after 1 retry).
