[Buildroot] [PATCH 1/1] package/systemd: hybrid cgroupfs hierarchy for docker compatibility

Docker fails to start with "Devices cgroup isn't mounted" as of systemd 243.
According to the systemd documentation:
systemd now defaults to the "unified" cgroup hierarchy setup during
build-time, i.e. -Ddefault-hierarchy=unified is now the build-time default.
Previously, -Ddefault-hierarchy=hybrid was the default. [...] Downstream
production distributions might want to continue to use
-Ddefault-hierarchy=hybrid (or even =legacy) for their builds as unfortunately
the popular container managers have not caught up with the kernel API changes.
Changing this option to "hybrid" or "legacy" fixes the Docker startup.
