If no output file type is specified via the -O parameter, guess the
desired file type by looking at the file name extension.
If that provides no useful hints, assume "dtb" as long as the input
type is "dts". Any other input type will lead to "dts" being used as
the guessed output type.
Any explicit specification of the output type will skip this guessing.
