Mahe Tardy ed3e469d02 bpf: fix cgroup_skb prog test run direct packet access ...

This is needed in the context of Tetragon to test cgroup_skb programs
using BPF_PROG_TEST_RUN with direct packet access.

Commit b39b5f411d ("bpf: add cg_skb_is_valid_access for
BPF_PROG_TYPE_CGROUP_SKB") added direct packet access for cgroup_skb
programs and following commit 2cb494a36c ("bpf: add tests for direct
packet access from CGROUP_SKB") added tests to the verifier to ensure
that access to skb fields was possible and also fixed
bpf_prog_test_run_skb. However, is_direct_pkt_access was never set to
true for this program type, so data pointers were not computed when
using prog_test_run, making data_end always equal to zero (data_meta is
not accessible for cgroup_skb).
