[libfuzzer] Removing coverage-related flags from asan options.

Summary:
Reasons to remove are twofold:
- we don't really need coverage=1 for libfuzzer operation
- makes controlling coverage for fuzzer processes non-trivial.

Use std::piecewise_constant_distribution instead of ad-hoc binary search.
...
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.
