[OE-core] [PATCH v2] selftest: Test needed to verify postinst order

[Francisco Pedraza]

It verifies the following:

1. Compile a minimal image.
2. The compiled image will add the layer with the recipe postinst,
previously created at:
"meta-selftest/recipes-test"
3. Run QEMU.
4. Validate the task execution order.
[YOCTO #5319]
