PR install/54480: when upgrading a system and re-mounting the target /
with proper options, and the installed system does not use NAME= syntax
in fstab(5), use the device name we used to get here, instead of the
name from fstab, it might be different to what the real system calls the
device (compact flash root showing up as wd0 native, but sd? on the
card reader used for updating it right now).
This is an abuse of the upgrade functionality and in general pretty dangerous
when multiple devices are used in the upgraded fstab (e.g. separate /usr),
and it used to work more by accident with the old code.
However, it is a quite usefull way to upgrade tiny systems with compact flash
root, and it used to work - so support it properly (as far as we can).
