Subject: [PATCH] core: move runtime directory removal into release_resource
handler
We already clear the various fds we keep from the release_resources()
handler, let's also destroy the runtime dir from there if this
preservation mode is selected.
This makes a minor semantic change: previously we'd keep a runtime
directory around if RuntimeDirectoryPreserve=restart is selected and at
least one JOB_START job was around. With this logic we'll keep it around
a tiny bit longer: as long as any job for the unit is around.
Conflict:NA
