Upgrading to dev builds is not idempotent on Solaris 11

https://github.com/puppetlabs/puppetlabs-puppet_agent/blob/master/manifests/init.pp#L172 munges package versions on Solaris 11 by stripping all letters (i.e.: 5.5.20.102.g9e5216a6 turns to 5.5.20.102.952166).

This in turn causes the version check here to fail: https://github.com/puppetlabs/puppetlabs-puppet_agent/blob/d26fab5cdcba8f96478d07012cbdcfe146161f0f/lib/puppet/provider/puppet_agent_end_run/puppet_agent_end_run.rb#L33

Gem::Version.new(...).release.version would strip the git SHA from the version, but in our case letters were already stripped, causing 5.5.20.102.952166 to be treated as the desired version (instead of 5.5.20.102, which would correspond to the aio_agent_build fact)

As far as I can tell, this peculiarity is limited to Solaris 11.
