pkg/bisect: Implement config bisection
Implement Linux kernel configuration bisection. Use bisected minimalistic
configuration in commit bisection. Utilizes config_bisect.pl script from Linux
kernel tree in bisection.
Modify syz-bisect to read in kernel.baseline_config. This is used as a "good"
configuration when bisection is run.
