bpf: honor env->test_state_freq flag in is_state_visited()
env->test_state_freq flag can be set by user by passing
BPF_F_TEST_STATE_FREQ program flag. This is used in a bunch of selftests
to have predictable state checkpoints at every jump and so on.
Currently, bounded loop handling heuristic ignores this flag if number
of processed jumps and/or number of processed instructions is below some
thresholds, which throws off that reliable state checkpointing.
Honor this flag in all circumstances by disabling heuristic if
env->test_state_freq is set.
