Title: Fix issue 16174 (http://projects.puppetlabs.com/issues/16174) resize ext4 on rhel5 famliy systems

On RHEL 5 family systems ext4 filesystems can not be resized using resize2fs.
resize4fs from e4fsprogs is required.
This update checks that the system is rhel5 with a blockid of ext4 and calls resize4fs instead.
