binfmt: Add a configuration flag to store the module filename
This flag can be used to store the filename of a loaded module or
executable in binfmt. The filename is useful for example in debugging.
For example, gdb or a jtag debugger can be configured to automatically
fetch the symbols for the currently executing module.
