socket tests: Serialize sonewconn_overflow

It relies on being able inspect the dmesg buffer to see whether the
kernel logged certain messages. If it's interleaved with tests that
generate large amounts of console output (e.g., GELI tests), then it can
fail spuriously.

tests: Add ktrace capability violation test cases

Introduce regression tests for ktrace(2) that target capability
violations.

These test cases ensure that ktrace(2) records these violations:
- CAPFAIL_NOTCAPABLE
- CAPFAIL_INCREASE
- CAPFAIL_SYSCALL
- CAPFAIL_SIGNAL
- CAPFAIL_PROTO
- CAPFAIL_SOCKADDR
- CAPFAIL_NAMEI
- CAPFAIL_CPUSET

A portion of these test cases create processes that do NOT enter
capability mode, but raise violations. This is intended behavior.
Users may run `ktrace -t p` on non-Capsicumized programs to detect
violations that would occur if the process were in capability mode.

kern: pts: do not special case closed slave side

This would previously return 1 if the slave side of the pts was closed
to force an application to read() from it and observe the EOF, but it's
not clear why and this is inconsistent both with how we handle devices
with similar mechanics (like pipes) and also with other kernels, such as
OpenBSD/NetBSD and Linux.

sockets: add MSG_TRUNC flag handling for recvfrom()/recvmsg().

Implement Linux-variant of MSG_TRUNC input flag used in recv(), recvfrom() and recvmsg().
Posix defines MSG_TRUNC as an output flag, indicating packet/datagram truncation.
Linux extended it a while (~15+ years) ago to act as input flag,
resulting in returning the full packet size regarless of the input
buffer size.
It's a (relatively) popular pattern to do recvmsg( MSG_PEEK | MSG_TRUNC) to get the
packet size, allocate the buffer and issue another call to fetch the packet.
In particular, it's popular in userland netlink code, which is the primary driving factor of this change.

This commit implements the MSG_TRUNC support for SOCK_DGRAM sockets (udp, unix and all soreceive_generic() users).
