Mike Tsao b4956d363a openpgp: serialize correct bitlength for generated ECC keys

Rather than rounding the `type || X || Y` byte sequence to the next
8-bit boundary, packet.NewECDSAPublicKey() now rounds the X and Y
coordinates individually, then adds the bitlength 3 of type 4
(compressed). For NIST P-256, this leads to a bit length of 515,
rather than 520. GnuPG calculates 515 as well, and
https://tools.ietf.org/html/rfc6637#section-6 explicitly states that
"the exact size of the MPI payload is 515 bits for 'Curve P-256,'"
so the new formula is consistent.

Fixes golang/go#23460
