Change https://go-review.googlesource.com/c/sys/+/56172 did not run
./mkall.sh after modifying syscall_linux.go. This change simply runs
./mkall.sh to correctly generate the modified files.

Note that the previous change simply reordered a few functions, so the
functions are simply reordered in the generated files.

This commit relaxes SendmsgN behavior of introducing a dummy 1-byte
payload when sending ancillary-only messages.
The fake payload is not needed for SOCK_DGRAM type sockets, and actually
breaks interoperability with other fd-passing software (journald is one
known example). This introduces an additional check to avoid injecting
dummy payload in such case.

Capsicum support was added by https://golang.org/cl/47290, but only for
amd64. This broke the freebsd/386 build which was subsequently fixed by
http://golang.org/cl/51270. However, even with this fix the tests still
fail to build due to the missing Capsicum functions and types.

Fix the build/test on freebsd/386 for real by re-running mkall.sh on
FreeBSD 11.1-RELEASE (inside VirtualBox) to get all the Capsicum
functions and types.

Some zerrors constants were removed or converted to enums in the FreeBSD
headers. Manually move them to a dedicated file. Do the same for amd64,
where these constants were removed by accident in
https://golang.org/cl/47290.
