device-tree.bbclass: Add support to compile overlays separately

Currently only dts files are considered when looping through files to
compile. Modifying the loop to compile other files that are overlays.
Also surrounding this check with a try block as the function to find
overlays parses the file for a '/plugin/' tag, and there may be files in
the DT_FILES_PATH directory that are not parseable.
