Subject: [PATCH] systemctl: suppress warning about missing /proc/ when
--no-warn
Follow-up for 0f958c8d4fc13ed1c1af928b2a7d91d31c7576eb.
systemctl is called many times by dnf or so, and missing /proc/ is not
a user's fault, but package manager's issue.
With this commit, we can suppress the warning by updating rpm macros if
necessary.
(cherry picked from commit 91dfb74ef5e38625dada2c2a6ae30152e64c3f5b)
