libsepol/cil: Mark as abstract all sub-blocks of an abstract block

Browse Source 
If a block is marked as abstract, then it will be skipped during
every pass after blockabstracts are resolved (only tunables,
in-befores, and blockinherits are before blockabstracts), so mark
all of its sub-blocks as abstract to reflect their actual status.
