* debian/rules, Makefile:
  - fix the build for gccgo

* pollen.go:
  - calculate tag checksum first
* pollinate:
  - remove unused variable $cmd
  - ensure global tag file is readable
* debian/pollinate.default:
  - add helpful debug info to user agent, similar to chrome and firefox,
    optional and configurable in /etc/pollinate/default
* debian/pollinate.default:
  - there seem to be some odd errors (long delays) when curl uses
    whitespace in the user agent string
* debian/pollinate.upstart:
  - our upstart job should start on starting cloud-init, to ensure that
    we get run before generating SSH keys
