Subject: [PATCH] Support logging to stdout for running under systemd
If bootmac is running under systemd, sending output to `logger` usually
means that the output is not sent to journald, and is lost. This can
make debug more difficult. The var tested here is one that systemd sets
when running a daemon (see `man systemd.exec`.)
