[Libguestfs] [guestfs-tools PATCH 3/3] inspector: test /dev/mapper/VG-LV translation in LUKS-on-LVM test

[Laszlo Ersek]

In the LUKS-on-LVM virt-inspector test, run virt-inspector one more time,
now with such "--key" options that exercise the recent "/dev/mapper/VG-LV"
-> "/dev/VG/LV" translation (unescaping) from libguestfs-common. Verify
that virt-inspector outputs the same XML as it did when we passed it the
"/dev/VG/LV" format "--key" options.
