commands: add new stat command

We have a couple of commands to help with debugging the VFS:
ll, devinfo, devlookup, but we lack a command that can just dump all
information we have in a struct stat or struct cdev. Add stat as such a
command. For most uses, it's not needed, but it can come in handy for
development. The stat_print and cdev_print functions underlying it are
exported, so they can called for debugging purposes.
