imagemagick: adds ptest for imagemagick recipe

Backport of the commit 96b97c0c6490b713b559a4e82bd699a2ebe357d3 from master

This patch enables ptest for imagemagick, improving test coverage for
continuous integration and runtime validation.
No functional changes are introduced to the core package.

The logic used is :
- We check if the required tools are present or not
- We used convert to create an raw RGB file
- The created RGB is then converted to PNG using convert
- We re-gerenate RGB from PNG and compare the original and re-generated RGB
- Enabled the ptest in ptest-packagelists-meta-oe.inc as
  suggested by Gyorgy Sarvari and incorporated logging suggestion
- This was done as standard imagemagick test like drawtest requires manual
  internetion to verify the file.
