golang.org/x/sys now requires go1.17 as a minimum, and otherwise
fails:
Error: ../../../go/pkg/mod/golang.org/x/sys@v0.2.0/unix/syscall.go:83:16: undefined: unsafe.Slice
Error: ../../../go/pkg/mod/golang.org/x/sys@v0.2.0/unix/syscall_linux.go:2256:9: undefined: unsafe.Slice
Error: ../../../go/pkg/mod/golang.org/x/sys@v0.2.0/unix/syscall_unix.go:118:7: undefined: unsafe.Slice
Error: ../../../go/pkg/mod/golang.org/x/sys@v0.2.0/unix/sysvshm_unix.go:33:7: undefined: unsafe.Slice
unsafe.Slice was added in go1.17; https://pkg.go.dev/unsafe#Slice
Now that go1.17 is the minimum version, we cal also replace the deprecated io/ioutil
package (which was deprecated in go1.16).

The syscall package is deprecated and no longer updated as per
https://golang.org/pkg/syscall/. Use the golang.org/x/sys/unix package
instead, which also provides a wrapper for SYS_SETNS, so the syscall
number encoding depending on runtime.GOARCH can be dropped.
