Avoid error in ooxml for non-office zip files

oleobj cannot detect yet that these are open office, but it can now
treat them like regular zip files and find embedded objects in them.

Samples are harmless, were created by me.

Firstly, not all zip files are ooxml files;
Secondly, show in debug mode that ole file is analyzed by debug-logging
  stream names

One actually was an error (missing return from is_ooxml)

Not sure whether this copying is necessary at all...

Usually, did check for xml first, so if is not zip then the message
was correct. But might change and function might be called from
elsewhere.

This has to be present for Office OpenXML files but is not there e.g.
for OpenOffice files (odt, ...).

Can still analyze the file without this.

Every logging call can have an optional arg type='...' which is
ignored when logging to text but shows in json output. The "type"
of regular logging output in json is type='msg'.

Added 2 messages with different type, adjusted existing test, created
2 new ones.

This is a start to bring back some structure into the json output.

Might not be a permanent solution, need to further discuss in PR 308

Output "DDE Links:" makes another "DDE-Link " prefix unnecessary and
parsing of output harder.
