fix syslog logging on FreeBSD 

Due to capsicum(4), opening the log on-demand via syslog(3) fails.
openlog(LOG_NDELAY) forces the log to be opened immediately, before we
enter capsicum.

This doesn't affect OpenBSD (where pledge(2) doesn't stop syslog) nor
linux (where the log process is not sandboxed.)

Reported by Karl Jeacle, thank you!
