Richard Marko 6c9df40a4b nixos/device-tree: improve overlays support
Now allows applying external overlays either in form of
.dts file, literal dts context added to store or precompiled .dtbo.

If overlays are defined, kernel device-trees are compiled with '-@'
so the .dtb files contain symbols which we can reference in our
overlays.

Since `fdtoverlay` doesn't respect `/ compatible` by itself
we query compatible strings of both `dtb` and `dtbo(verlay)`
and apply only if latter is substring of the former.

Also adds support for filtering .dtb files (as there are now nearly 1k
dtbs).
