[Buildroot] [PATCH v3] exiv2: new package

[Nicolas Serafini]

Add support for Exiv2 library and utility to manage image metadata

Exiv2 can be built in GPLv2+ or commercial version. But in commercial
version the Nikon lens name database and the NLS support has to be
disabled for copyright reason.

Changes v2 -> v3:
  - New Config.in option for Nikon lens name database
  - Update/Add comments on copyright in commercial version
  - Commercial licence removed when not selected (copy/paste bug)

Changes v1 -> v2:
  - Make conditional GPLv2+/commercial license
  - Wrap Config.in to 72 columns
  - Leave default value for package source
