[yocto] [PATCH] run-config: Reverse the oder of remove layers

[Aaron Chan]

This patch fixes the "Collection Error during parsing layer conf"
when a parent layer is accidentally added before depend layers.
When removing layers from bblayers, we should not be following
the same sequence of adding the layers, it should be done in a
reversed order. This is an assumption that the layers have their
dependent layers added before the parent layers are added.
In general, the parent layer require to be remove first before
its child dependencies layers.
