create-diff-object: Add support for applied/reverted marker

With version 2 of a payload structure additional field is supported
to track whether given function has been applied or reverted.
There also comes additional 8-byte alignment padding to reserve
place for future flags and options.

The new fields are zero-out upon .livepatch.funcs section creation.
