Cleaning up TODO's. If we're on >= 5.11 we need userxattr so check
the kernel version to skip the manual check via mounting. It feels
odd to use contrib/seccomp here but the alternative is pulling that
kernel parsing code out into the main pkgs. Another is using the moby
parser but that's in moby/moby which is also a dep we don't want here..

The io/ioutil package has been deprecated as of Go 1.16, see
https://golang.org/doc/go1.16#ioutil. This commit replaces the existing
io/ioutil functions with their new definitions in io and os packages.
