a55654d598 core: add new ConditionNeedsUpdate= unit condition
This new condition allows checking whether /etc or /var are out-of-date
relative to /usr. This is the counterpart for the update flag managed by
systemd-update-done.service. Services that want to be started once after
/usr got updated should use:

        [Unit]
        ConditionNeedsUpdate=/etc
        Before=systemd-update-done.service

This makes sure that they are only run if /etc is out-of-date relative
to /usr. And that it will be executed after systemd-update-done.service
which is responsible for marking /etc up-to-date relative to the current
/usr.

ConditionNeedsUpdate= will also checks whether /etc is actually
writable, and not trigger if it isn't, since no update is possible then.

b77c08e06b condition: split out most of condition handling into libsystemd-shard
The parts that require linknig to libcap, libselinux and friends stays in libsystemd-core.
