We need this to control whether `('matrix-' + matrix_homeserver_implementation + '.service')`
would get injected into `devture_systemd_service_manager_services_list_auto`

This was useful when the order of these roles in relation to Synapse
mattered (when we were injecting stuff into Synapse variables during
runtime). This is no longer the case since 0ea7cb5d1812a88, so all of
this can be removed.

These `init.yml` (now `inject_into_nginx_proxy.yml`) tasks do not need
to `always` run. They only need to run for `setup-all` and
`setup-nginx-proxy`. Unless we're dealing with these 2 tags, we can
spare ourselves a lot of work.

This patch also moves the `when` statement from `init.yml` into
`main.yml` in an effort to further optimize things by potentially
avoiding the extra file include.

These are not even caused by Archlinux, but by running buggy Ansible on old Ubuntu
while targeting modern servers (like Archlinux, but also others, ..).

We shouldn't employ ugly workarounds like this. We should tell people to
avoid running buggy Ansible or bad distros like Ubuntu, even.

This reverts commit 4146c48f6a.
