Bogus serial string in subiquity install wwn-eui.*

Curtin is prefixing 'wwn' for configs which specify a wwn value. The wwn value does not include the string 'wwn' and udev rules for persistent disks prefix the wwn with wwn-<WWN value).

However, for NVME, udev may export ID_WWN=eui.XXXX value, and it may well be a WWN, it does not get symlinked as a wwn-<WWN> symlink in /dev/disk/by-id at all.

This bug is fixed with commit d55dbb04 to curtin on branch master.
