openpgp/packet: fix AES-192 encrypted session keys

The existing implementation checks to see if the session key size is a
multiple of the cipher blocksize. This fails for AES-192, which has a
keysize of 24 bytes and a 16 byte block size. Instead it should simply
check to ensure that the Session Key length is equal to the cipher
KeySize.

Fixes golang/go#17060
