syz-fuzzer: prefer to mutate instead of generate

Browse Source 
Currently we generate 1 program per 9 mutations.
Do it per 99 mutations.
Benchmark shows both coverage increase and corpus reduction:

                    baseline     generate100            diff
coverage               65467           65569             102
corpus                 35423           35363             -60
