puppetmaster: fixup to $is_labs_puppet_master ref

Commit ca0c74bb fixed the reference to the $is_labs_puppet_master
variable. The geoip class gained it in the meantime; fix it here too.

geoip: don't filebucket geoip databases

GeoIP databases are a whopping 88M now, most of which changes every
week. Filebucketing them up on change is stupid, as we can always
recover past versions anyway and a waste of space across the fleet.

clientbucket on e.g. analytics1001 even before the latest changes (so
for about half the data) is 765M.

Set backup => false to the directory to fix this.
