util.ringbuffer: find(): Fix find logic bugs
If the buffer was full, find() would return earlier (wpos == rpos). Checking
blen is the better way to test if the buffer is empty.
Secondly, the loop scanned for blen - l, but if l (length of needle) was
larger than the buffer length, this calculation would underflow and cause a
lot of spinning.
New tests have been added to cover various edge cases of :find().
