firewalld: Mock IpTables::{Add|Delete}AcceptRule methods.
This CL paves the way to launch 'ip(6)tables' using Minijail. We cannot
use the current approach of providing test-only binaries because Minijail
will not work when running as non-root (such as in unit tests). Therefore,
we need to mock {Add|Delete}Accept.
Also add an Exec() method to wrap the Minijail invocation in the future,
and clean up some of the unit tests.

TEST=Existing unit tests.
