[meta-zephyr][PATCH 1/2] zephyr-core/zephyr-kernel: Refactor zephyr-image and zephyr-sample

[Peter Hoyes <peter.hoyes@arm.com>]

From: Peter Hoyes <Peter.Hoyes@arm.com>

At the moment:
 * zephyr-image.inc depends on zephyr-sample.inc, which doesn't really
   make sense.
 * zephyr-image.inc inherits testimage, even though it may not be
   required.
 * Out-of-tree Zephyr apps have to include zephyr-sample.inc in order to
   deploy the binaries, which is confusingly named if your application
   isn't a "sample".

Do some minor refactoring to untangle the above. Now:
 * zephyr-sample.inc depends on zephyr-image.inc
 * zephyrtest.bbclass inherits testimage.
 * Out-of-tree Zephyr apps can include zephyr-image.inc

Additionally, remove QEMU_BIN_PATH, as recent Zephyr versions now pick
up the QEMU binary automatically from PATH.
