Don't extract any top-level files in a package that start with '.'

For future possibilities, don't extract any files that start with '.'.
This will allow us to add features such as the ChangeLog viewing without
having to wait to include these files in packages, because older versions
of pacman will be forward compatable with 'hidden' files at the root level
of the package.
