When the daemon runs as a different user (e.g. via systemd), the client
cannot read /proc/<pid>/environ due to permissions. Fall back to
parsing the cmdline for -D / --state-dir flags, which are world-readable.
Fixes 'error: no logs for <service>' when client and daemon run as
different users.
v0.1.1
sets SIGTERM death signal in each child before exec, so if the
daemon exits (even by crash/SIGKILL), all managed services receive
SIGTERM and terminate. adds libc dependency for prctl.
includes getppid() == 1 check to handle the fork/prctl race.
