makepkg: allow less than the full fingerprint in validpgpkeys
I found this feature confusing, and the documentation wasn't any help.
It was pointed out to me on IRC that validpgpkeys expects full
fingerprints, and won't accept shorter forms. This makes the
documentation insufficient, and the variable name itself misleading.
This patch bolsters the documentation to explain more about what the
contents should be, and implements suffix matching to allow matching on
shorters fingerprint suffices. Now, when makepkg tells you that a key
ID isn't valid, it's sufficient to manually check the key ID against
the known good ID, and add it as is to validpgpkeys.
