Zbigniew Jędrzejewski-Szmek e27c382bf0 report-basic: expose os-release fields as metrics
Add io.systemd.Basic.OSRelease metric families that reports select fields
from os-release.

$ cat /etc/os-release

$ varlinkctl call --more ./build/systemd-report-basic io.systemd.Metrics.List {} | jq --seq -c
...
{"name":"io.systemd.Basic.OSRelease.NAME","value":"Fedora Linux 44 (Workstation Edition)"}
{"name":"io.systemd.Basic.OSRelease.ID","value":"fedora"}
{"name":"io.systemd.Basic.OSRelease.CPE_NAME","value":"cpe:/o:fedoraproject:fedora:44"}
{"name":"io.systemd.Basic.OSRelease.VARIANT_ID","value":"workstation"}
{"name":"io.systemd.Basic.OSRelease.VERSION_ID","value":"44"}
{"name":"io.systemd.Basic.OSRelease.SUPPORT_END","value":"2027-05-19"}

I picked the fields that contain useful information about the specific
version/image/variant/experiment/flavour of the system. Also, either
NAME or PRETTY_NAME is included. This one is intended for human readers
to be able to identify the OS version easily.
