selftests/bpf: Test skops->skb_hwtstamp

Browse source

This patch tests reading the skops->skb_hwtstamp field.

A local test was also done such that the shinfo hwtstamp was temporary
set to a non zero value in the kernel bpf_skops_parse_hdr()
and the same value can be read by the skops test.

An adjustment is needed to the btf_dump selftest because
the changes in the 'struct bpf_sock_ops'.
