First, I should point out that the whole purpose of syslog(3) is
to do the flexible directing of different daemons' logs to different
places, including in chroots.

That said, adding logging to stderr is also very trivial, given the
current code.  I have updated the two files on my website [1] to include
this.  Just set environment variable WG_LOG_DEST to "stderr" and then
start wireguard-go.

Please test.  If this works as desired, I will update the git patch
that I sent in yesterday.
