Policy booleans allow adjusting certain policy rules at runtime
(including whether changing policy booleans is allowed). The new
option allows setting their defaults at build time.
A monolithic policy (like built by package/refpolicy) does not support
persistent changes to policy booleans, so changing the defaults is
required to make changes across boots. Adjusting policy/booleans.conf
after "make conf" is intended for that purpose [1, 2].
