Since we renamed Camlistore to Perkeep, we also renamed the docker image
deployed by the launcher, as well as the systemd service that this
docker image runs in.
This means existing users on GCE do not get updates when they restart
the service or reset their instance.
This change adds a check and a function that allows perkeepd to fix the
user-data metadata of its own GCE instance, which is where the names
mentioned above are defined.
Therefore, if we deploy a new camlistore docker image containing that
code, the existing users should get a server capable of self-fixing its
own instance into a perkeep one.

We migrated to using the long form for key IDs sometime ago, but we
never updated the client of the gpgchallenge accordingly, so in
functions that take a keyID as an argument, it would fail to find the
given long keyID within a key ring.
However, for usability reasons, we want to keep the short form in the
hostname of the instance (and hence as the DNS entry), so we revert to
using the short form when perkeepd is setting its host name.
