mptcp, btf: Add struct mptcp_sock definition when CONFIG_MPTCP is disabled
The btf_sock_ids array needs struct mptcp_sock BTF ID for the
bpf_skc_to_mptcp_sock helper.
When CONFIG_MPTCP is disabled, the 'struct mptcp_sock' is not
defined and resolve_btfids will complain with:
[...]
BTFIDS vmlinux
WARN: resolve_btfids: unresolved symbol mptcp_sock
[...]
Add an empty definition for struct mptcp_sock when CONFIG_MPTCP
is disabled.
Fixes: 3bc253c2e652 ("bpf: Add bpf_skc_to_mptcp_sock_proto")
