units: enable systemd-report-basic.socket by default

In https://github.com/systemd/systemd/pull/41688 we merged metrics
and facts for systemd-report. However while some metric sources
are enabled by default (like `io.systemd.{Manager,Network}`) the
`io.systemd.Basic` service is not enabled by default.

This commit changes this and enables it by default.

We could also enable the systemd-report-cgroup.socket but that sends
a lot more data not sure that is a good default.
