Alejandro Hernandez Samaniego e9f9ca2da7 baremetal-image: Fix post process command rootfs_update_timestamp
When running:

execute_pre_post_process(d, d.getVar(ROOTFS_POSTPROCESS_COMMAND))

rootfs_update_timestamp is run, which assumes that rootfs/${sysconfdir}
is already created (usually done through the do_rootfs task on linux).

This causes the build to fail if ${sysconfdir} does not exist.

This may be overlooked if debug-tweaks is enabled since some other
commands are added, one of which creates the required path
(see postinst_enable_logging).

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.
