If there is more than one file name specified on the command line,
assume it is the output file name.
This allows to use a more intuitive cp-style command line syntax,
which (together with the input type guessing) allows something like:
$ dtc input.dts output.dtb
(or the other way round) to cover the most common usage scenarios.
