    postinst: Add a test case to verify postinst scripts behavior

+        Summary:        The purpose of this test case is to verify Post-installation
+                        scripts are called when roofs is created and also test
+                        that script can be delayed to run at first boot.
+        Dependencies:   NA
+        Steps:          1. Add proper configuration to local.conf file
+                        2. Build a "core-image-full-cmdline" image
+                        3. Verify that file created by postinst_rootfs recipe is
+                           present on rootfs dir.
+                        4. Boot the image created on qemu and verify that the file
+                           created by postinst_boot recipe is present on image.
+                        5. Clean the packages and image created to test with
