[PATCH 5/5] common/log.c: use vscnprintf() in log_dispatch()

[Rasmus Villemoes]

We have to use the *printf variant which returns the strlen() of the
resulting string, not the
how-much-would-have-been-printed-given-enough-space, in order to use
that value to inspect the last character in the string.
