fix segfault in svlogd discovered on armv7hf-musl.
Code in svlogd.c allocates some memory at startup which is
not zeroed, and other code was using those garbage values.
I have no idea why this has never caused a problem before, but
for me, svlogd consistently segfaults on armv7hf-musl when
it is called by socklog.
