[Adrian Perez de Castro]

Fixes:
http://autobuild.buildroot.net/results/faa23c0e648b916d0fb01adb95948234d6db7a71/

The JSON::PP Perl module is used at build time by the webkitgtk
and wpewebkit packages.

v1 -> v2:
- Intead of making the package depend on host-perl, check for the module
  in the dependencies.sh script to avoid making the build slower. The
  module has been in core Perl since 2013.
