cbfstool: add optional -m ARCH to extract 

In order to prepare allowing for one to extract a stage
into an ELF file provide an optional -m ARCH option. This
allows one to indicate to cbfstool what architecture type
the ELF file should be in.

Longer term each stage and payload will have an attribute
associated with it which indicates the attributes of
the executable.
