standalone etherpad

This fixes a regression since the change done in c1c152f7ac.
When another role (say `matrix-jitsi`) included `roles/custom/matrix-base/tasks/util/ensure_openssl_installed.yml`,
which then included `{{ role_path }}/tasks/util/ensure_openssl_installed_DISTRO.yml`,
that `role_path` variable would end up being the parent role
(`matrix-jitsi`) and not the `matrix-base` role, so we'd get a failure.

An alternative solution may have been to avoid using `role_path`, but
importing roles properly (like we've done in this patch) sounds like a better way.

Unfortunately, `import_role` fails if `tasks_from` is something like
`util/ensure_openssl_installed` (containing a `/`), so I had to move
these utils out of `util/`.

This avoids Ansible trying to ensure `community.general.pacman` is
available, even if that module will never run (because `when` says so).

With this change, trying to run the playbook should report an error that
looks like this:

> The offending line appears to be:
>
>     # Most of the roles below are not distributed with the playbook, but downloaded separately using `ansible-galaxy` via the `make roles` command (see `Makefile`).
>     - role: galaxy/com.devture.ansible.role.playbook_help
>       ^ here

.. with that comment included, which might help some people who missed
the `make roles` part.
