Subject: [PATCH] user-runtime-dir: downgrade a few log messages to LOG_DEBUG
 that we ignore

As the comments already say it might be quite likely that
$XDG_RUNTIME_DIR is not set up as mount, and we shouldn't complain about
that.

Moreover, let's make this idempotent, so that a runtime dir that is
already gone and is removed again doesn't cause failure.

(cherry picked from commit 3a13442bbf72e7ebdd0b4d60c2922ea7c5cc9496)
