Fixing #2789 puppetrun fails without --tag

Puppet::Transaction was handling "tags" strings differently depending on
whether they came in from Puppet[:tags] or another source.
This was causing puppetrun's tags to be misparsed if there was not
exactly one --tag parameter.

I've moved the code to Util::Tagging.
