nixos/hardware/device-tree: make overlays more reliable
This make the process of applying overlays more reliable by:

1. Ignoring dtb files that are not really device trees. [^1]

2. Adding a `filter` option (per-overlay, there already is a global one)
   to limit the files to which the overlay applies. This is useful
   in cases where the `compatible` string is ambiguous and multiple
   unrelated files match.

Previously the script would fail in both cases.

[^1]: For example, there is dtbs/overlays/overlay_map.dtb in the
      Raspberry Pi 1 kernel.
