selftests/bpf: Test bpf_skb_adjust_room on CHECKSUM_PARTIAL
When the bpf_skb_adjust_room() shrinks the skb such that its csum_start
is invalid, the skb->ip_summed should be reset from CHECKSUM_PARTIAL to
CHECKSUM_NONE.
The commit 54c3f1a81421 ("bpf: pull before calling skb_postpull_rcsum()")
fixed it.
This patch adds a test to ensure the skb->ip_summed changed from
CHECKSUM_PARTIAL to CHECKSUM_NONE after bpf_skb_adjust_room().
