Apply self-imposed path length also to root CAs

Also, some readers of the code find starting the count at 1 for EE
cert confusing (since RFC5280 counts only non-self-issued intermediate
CAs, but we also counted the leaf).  Therefore, never count the EE
cert, and adjust the path length comparison accordinly.  This may
be more clear to the reader.
