Subject: [PATCH 64/72] script: be sensitive to another SIGCHLD ssi_codes
The current signalfd handler cares on CLD_EXITED only. It's pretty
insufficient as there is more situations (and codes) when child no
more running.
Addresses: https://github.com/karelzak/util-linux/issues/686
Upstream: http://github.com/util-linux/util-linux/commit/27afe5016842c22d256ea9f88b598d637ca0df84
