selftests/bpf: Verify ca_name of struct mptcp_sock
This patch verifies another member of struct mptcp_sock, ca_name. Add a
new function get_msk_ca_name() to read the sysctl tcp_congestion_control
and verify it in verify_msk().
v3: Access the sysctl through the filesystem to avoid compatibility
issues with the busybox sysctl command.
v4: use ASSERT_* instead of CHECK_FAIL (Andrii)
v5: use ASSERT_STRNEQ() instead of strncmp() (Andrii)
