[OE-core] [PATCH] device-tree.bbclass: Add support to compile overlays separately

[Jaewon Lee]

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.
