Better handle creation of UUID for claiming. (#11974)
* Properly check for the availability of `uuidgen` before blindly using
it.
* Fall back on Linux to the kernel-provided interface for generating
UUIDs if `uuidgen` is not present.
* Provide a more useful error message if we can’t use either option.
