selftest: af_unix: Add non-TCP-compliant test cases in msg_oob.c.
While testing, I found some weird behaviour on the TCP side as well.
For example, TCP drops the preceding OOB data when queueing a new
OOB data if the old OOB data is at the head of recvq.
# RUN msg_oob.no_peek.ex_oob_drop ...
# msg_oob.c:146:ex_oob_drop:AF_UNIX :x
# msg_oob.c:147:ex_oob_drop:TCP :Resource temporarily unavailable
# msg_oob.c:146:ex_oob_drop:AF_UNIX :y
# msg_oob.c:147:ex_oob_drop:TCP :Invalid argument
# OK msg_oob.no_peek.ex_oob_drop
ok 9 msg_oob.no_peek.ex_oob_drop
# RUN msg_oob.no_peek.ex_oob_drop_2 ...
# msg_oob.c:146:ex_oob_drop_2:AF_UNIX :x
# msg_oob.c:147:ex_oob_drop_2:TCP :Resource temporarily unavailable
# OK msg_oob.no_peek.ex_oob_drop_2
ok 10 msg_oob.no_peek.ex_oob_drop_2
This patch allows AF_UNIX's MSG_OOB implementation to produce different
results from TCP when operations are guarded with tcp_incompliant{}.
