Add const to both arguments of X509_certificate_type() and clean up

a little:

Use X509_get0_pubkey() in place of X509_get_pubkey() and EVP_PKEY_free().
Check return value of the former in the appropriate place and simplify the
logic for dealing with the potentially NULL pkey argument (includes a neat
tweak from jsing). Finally, kill an ugly comment that has been rotting for
twenty years and merge the lines around it.

tested in a bulk build by sthen
ok jsing
