Subject: [PATCH] core/manager: print info about interesting signals

Information about signals which are not routinely received by systemd
are printed at info level. This should make it easier to see what is
happening in the system.

(cherry picked from commit a9244623f785f504f799407b0228dea9655e24cb)
