[RFC,v1,0/2] Fix non-TCP sockets restriction

Hello!
This patch fixes incorrect restriction of non-TCP bind/connect actions.
Added tests cover all protocols which were incorrectly restricted. But I'm
not sure this coverage is necessary (considering a little complication of
network selftests), probably checking a single protocol (e.g. MPTCP) will
be enough. WDYT?

Closes: https://github.com/landlock-lsm/linux/issues/40
