qemu_set_log_filename: filename argument may be NULL
NULL is a valid log filename used to indicate we want to use stderr
but qemu_set_log_filename (which is called by bsd-user/main.c) was not
handling it correctly.
That also made redundant a couple of NULL checks in calling code which
have been removed.
