Force Gentoo-based distros to use full pkg name
Remove platform-specific code from pkg state

Platform-specific code from #3019 has been moved to pkg_resource module.
This code may evolve a bit down the road. Presently it will only check
syntax if the package is coming from the portage tree via ebuild.
However, future support for entropy (binary pkg manager), as well as
expanding syntax checking for binary package files should be considered
TODO items.

Remove platform-specific code from pkg state
Only setup the console logger if we're not daemonizing. Fixes #3016.
Convert tabs to spaces. Refs #3015.
Don't touch closed ZMQ socket's and/or context's. Fixes #3015.

* On some occasions it seems that `salt.utils.event.SaltEvent.destroy()` is called twice and the errors exhibited on #3015 would show up on the second time we would try to set the linger socket option since that socket was already closed. So, even though on some parts of code which I changed in this commit weren't giving any problems, I ended up using the same recipe all around, if the socket is open, set the linger option and close it, plus, if open, also close the context.
