[libFuzzer] don't require seed in fuzzer::Mutate, instead use the global Fuzzer object for fuzzer::Mutate. This makes custom mutators fast

Summary:
Fix the issue with the most recently discovered unit receiving much less attention.
Note: I had to change the seed for one test to make it pass. Alternatively,
the number of runs could be increased. I believe that the average time of
'foo' discovery is not increased, just seed=1 was particularly convenient
for the previous PRNG scheme used.
