When using logger, log to stderr (via logger -s) only if connected to a (p|t)ty.
Log to stderr without trying to use logger if /dev/log is not a socket or the logger command is unavailable.
Also document that util-linux is now optional, and fix a small issue with unwanted output (override log, not logger, when suppressing "command not found" output while probing for available IP parsing/expansion implementations).
