CVE-2019-13113 (integer-overflow)
CVE-2019-13112 (integer-overflow)

CVE-2019-13108 (denial-of-service)

Log message:
exiv2: fix buildling on Darwin

Log message:
exiv2: Update to 0.72.1

pkgsrc notes:

upstream has changed their build system to cmake (and meson in the
case of gexiv2)

unfortunately the build system for exiv2-organize has rotted so it
has to be removed for now.

tested on various netbsd versions with gimp, I am expecting breakage,
sorry in advance.
