[Pkg-kde-extras] Bug#797119: exiv2: loses timezone information in XMP dates

As indicated in the upstream bug report, exiv2 has had for many years
a conversion function mapping exif tags and xmp properties. In exiv2
0.25, these mappings were updated to MWG standards.

MWG guidelines specify that Xmp.xmp.CreateDate be mapped to
Exif.Photo.DateTimeDigitized which cannot hold timezone data. Previous
versions of exiv2 mapped to Xmp.exif.DateTimeDigitized so the issue
did not get triggered for the test case.

A workaround might involve changing the test case to not use Xmp.xmp.CreateDate.

I have an associated issue in exiv2 to make these conversions more
complete and robust. I could use some help with that issue.
