daemon: fix infinite loop caused by SIGPIPE

If bxt_err() makes SIGPIPE, Buxton daemon falls into infinite loop
because bxt_err() is also used in signalfd callback when SIGPIPE is
received.
bxt_err() can makes SIGPIPE if Buxton daemon is launched by systemd
and stderr is redirected to systemd-journal socket.
