[OE-core] [PATCH 1/1] run-postinsts: fix issue with checking IMAGE_FEATURES

[Laurentiu Palcu]

The old implementation was wrong. It was not very generic and it checked
IMAGE_FEATURES while building the recipe, which led to various issues
with the generation of the final script. That is, the run-postinsts
script was generated once, while building the package for the first
time. Hence, any other changes to IMAGE_FEATURES, like removing/adding
'package-management' did not reflect in the final script.

This commit makes run-postinsts script autodetect the backend used for
creating the image, making it generic.
