don't skip cert check for an example & use HTTPS

This changes two URLs from http to https and it fixes a Dockerfile to
stop skipping certificate validation. It also adds the ca-certificates
package to that Dockerfile example.

archive: Handle capabilities in tar files

If a file has a security.capability set, we push this to the tar file.
This is important to handle in e.g. layer files or when copying files
to containers, as some distros (e.g. Fedora) use capability bits as
a more finegrained version of setuid bits, and thus if the capabilites
are stripped (and setuid is not set) the binaries will fail to work.

forbid chained onbuild, from & maintainer triggers

This changes the way onbuild works:
- forbids the chaining of onbuild instructions
- forbids the use of `onbuild from`
- forbids the use of `onbuild maintainer`

It also makes docker throw errors when encountering such triggers when
executing the triggers during `FROM`.

Three tests have been added:
- ensure that chained onbuild (`onbuild onbuild`) is forbidden
- ensure that `onbuild from` is forbidden
- ensure that `onbuild maintainer` is forbidden
