usr: add usr mounting as a late running hook

Mount separate /usr partitions voluntarily, as a late running hook.
This is an unfortunate patch that will no doubt result in some hatemail,
though it won't thoroughly break anyone to the point of not booting.

As a side effect, findmnt is no longer a requisite of the core /init, so
move it to the shutdown and usr hooks where it's required.
