[OE-core] [PATCH 2/2] logrotate: Add systemd support

[Romain Perier]

Currently, this recipe only supports daily scheduling via a cron job.
This commit adds support for systemd in the recipe, as the feature is
already supported on upstream. When the corresponding distro feature
is enabled the systemd variant will be used. The timer granularity and
its accuracy are also configurable.
