The SIGUNUSED constant was removed from golang.org/x/sys/unix in
https://go-review.googlesource.com/61771 as it is also removed from the
respective glibc headers.
This means the command
ctr tasks kill SIGUNUSED ...
will no longer work. However, the same effect can be achieved with
ctr tasks kill SIGSYS ...
as SIGSYS has the same value as SIGUNUSED used to have.

This mainly fixes Linux vs generic Unix differences, with some
differences between Darwin and Freebsd (which are close bit not
identical). Should make fixing for other Unix platforms easier.
Note there are not yet `runc` equivalents for these platforms;
my current use case is image manipulation for the `moby` tool.
However there is interest in OCI runtime ports for both platforms.
Current status is that MacOS can build and run `ctr`, `dist`
and `containerd` and some operations are supported. FreeBSD 11
still needs some more fixes to continuity for extended attributes.
