Always pad fingerprints to 16 characters
Fingerprints were not padded with zeros. This led to a ucert failure
when the first byte of the fingerprint is 00, as it expects the
fingerprint to have a constant length (and this expectation seems
reasonable to me).

sha512: fix bad hardcoded constant in sha512_final()
The SHA512 implementation shipped with usign uses a wrong hardcoded
numeric constant in the final block padding code.
An additional transform step must be done when there are at least
SHA512_BLOCK_SIZE - 16 = 112 bytes in the state buffer, however the
existing code incorrectly transformed buffer data larger than or
equal to 110 bytes as well, resulting in invalid hash calculations
when exactly 110 or 111 remaining bytes were left in the buffer.
To reproduce the issue, sign a plaintext file with a size of exactly
128 * N + 64 + 110 or 128 * N + 64 + 111 bytes using signify-openbsd
and attempt to verify the signature using usign:
$ signify-openbsd -G -n -p test.pub -s test.key
$ dd if=/dev/zero of=test.msg bs=1 count=$((64 + 110))
$ signify-openbsd -S -x test.sig -s test.key -m test.msg
$ usign -V -p test.pub -x test.sig -m test.msg
Fix this issue by replacing the bad numeric constanct with a macro
expression resulting in the proper value.
The fix has been verified by cross checking the intermedia hash
results with results from OpenSSL's SHA512 implementation and by
comparing the usign SHA512 code with the hashing code shipped with
signify-openbsd.
