log: rework log_syntax_invalid_utf8() a bit

Browse Source 
The macro used utf8.h functions without including that. Let's clean this
up, by moving that code inside of log.c.

Let's also make the call return -EINVAL in all cases. This is in line
with log_oom() which also returns a well-defined error code even though
it doesn#t take one.
