syz-manager: re-minimize a subset of corpus programs
The current fuzzing algorithm in syzkaller may preserve the poorly
minimized corpus programs forever - they trigger a lot of coverage and
will very likely survive all syzkaller restarts.
As a result, more than 18% of the current syzbot corpus programs are
larger than 25 calls, which is an unreasonably big figure.
Introduce a way to prevent the domination of the bigprograms in the
corpus.
Every corpus retriage, pick up to 50 seeds among the 10% largest corpus
programs and re-minimize them. Hopefully, this should reduce the
magnitude of the problem.
