Fix missing 0 prefix of GPG key id (#30245) (#30247)

Backport #30245 by @KN4CK3R

Fixes #30235

If the key id "front" byte has a single digit, `%X` is missing the 0
prefix.
` 38D1A3EADDBEA9C` instead of
`038D1A3EADDBEA9C`
When using the `IssuerFingerprint` slice `%X` is enough but I changed it
to `%016X` too to be consistent.
