vyos-router: dhcpv6: T3885: add alternative UUID source
Not all boards/devices ship the /sys/class/dmi/id/product_uuid file, thus a
fallback is used (e.g. on PCEngines APU4 board) which feeds the device specific
UUID from /sys/class/dmi/id/product_serial
(cherry picked from commit 224941480bb5e41ee6b43e3bf0f357568f18d44f)
