abipkgdiff: Respect 'create_abi_file_path' interface

  Currently we may run into this:

    [...]
    abipkgdiff: Could not create the directory tree to store the abi for '[...]'
    abipkgdiff: Writting ABIXML file '' ...
    abipkgdiff: Wrote ABIXML file '' OK
    abipkgdiff: Reading ABIXML file '' ...
    abipkgdiff: Could not read temporary ABIXML file ''
    ==== Error happened during self check of '[...]' ====
    [...]

That is, after a failed 'create_abi_file_path', we proceed with an empty
'abi_file_path' -- because that one only gets set "iff the function return
true".  So we ought to 'return abigail::tools_utils::ABIDIFF_ERROR' in that
case.

(It's likewise strange why 'create_write_context'/'write_corpus' succeed with
an empty 'abi_file_path', but that's for another day...)

	* tools/abipkgdiff.cc (compare_to_self): Respect
	'create_abi_file_path' interface.
