Bug#1063722: /usr/bin/autopkgtest-build-qemu: autopkgtest-build-qemu can create incorrect /etc/fstab

Package: autopkgtest
Version: 5.32

autopkgtest-build-qemu assumes that the output
of $(ls -1 /dev/mapper/loop* | sort | tail -1) is the root device for the
created image. This can fail if there are other devices matching that glob.

vmdb2 supports creating /etc/fstab based on the created and mounted
partitions in the image. I've attached a patch to use vmdb2's fstab
support. I've also opened a MR[1] with the same changes.
