On ARM, QEMU's virt machine exposes EFI firmware pflash devices as
'/machine/virt.flash0' and '/machine/virt.flash1'. The query-block
mapping only recognized the x86-style '/machine/system.flash*' paths, so
it failed to translate '/machine/virt.flash1' to 'efidisk0'. This made
live cloning fail with 'no block node found for drive 'drive-efidisk0'.'
Accept both system.flash* and virt.flash* paths for these devices.
