fix(machined): support USERDATA legacy fallback in OpenNebula driver

mcanevet · smira · commit eb6eb664a1c2 · 2026-03-18T20:57:24.000+04:00
The reference does USER_DATA="${USER_DATA:-${USERDATA}}". Talos only read USER_DATA, silently returning ErrNoConfigSource when a VM used the legacy USERDATA variable name.
