Chen Qi da263d9c7a image.bbclass: fix systemd_preset_all
Check the existence of systemd before using systemctl to preset units.
This is because even if 'systemd' is in DISTRO_FEATURES, it's possible
that systemd is not even installed. e.g. container-test-image in
meta-selftest layer.

As systemd DEPENDS on systemd-systemctl-native, the existence of systemd
also ensures the existence of systemd-systemctl-native.

This would fix the following test case when using systemd as the init
manager.

  containerimage.ContainerImageTests.test_expected_files

Also remove the IMAGE_EXTRADEPENDS setting, as nothing references this
variable.

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.
