Ricardo Ribalda Delgado 58589bc538 wic: Fix (again) partition files UIDs on multi rootfs images
Commit 450335ba5e73a375eb9932b4c4cf37979640dbfc copies the pseudo
database to the working directory in order to have ownership information
when the filesystem is generated.

Unfortunately this does not work anymore. The filenames on the database
are absolute and there is no information about the new directory.

Instead of fixing the database, we could redo a bit the way we patch the
fstab file. Now I am saving the old contents of fstab, modifying the
file and then reverting the changes on exit.

This is faster than the previous approach, although it can cause
indeterminism if the application is killed before finishing.

QEMU Emulation Targets
======================

To simplify development, the build system supports building images to
work with the QEMU emulator in system emulation mode. Several architectures
are currently supported in 32 and 64 bit variants:

  * ARM (qemuarm + qemuarm64)
  * x86 (qemux86 + qemux86-64)
  * PowerPC (qemuppc only)
  * MIPS (qemumips + qemumips64)

Use of the QEMU images is covered in the Yocto Project Reference Manual.
The appropriate MACHINE variable value corresponding to the target is given
in brackets.
