graphics/php-imagick: update to 3.4.4

pkgsrc change: make DESCR pkglint clean.

3.4.4 (2019-05-02)

- The 3.4.4 release is intended to be the last release (other than small
  bug fixes) that will support either PHP 5.x, or ImageMagick 6.x. The
  next planned release will be PHP > 7.0 and ImageMagick > 7.0 at least,
  if not higher.

- Added:
  * function Imagick::optimizeImageTransparency()
  * METRIC_STRUCTURAL_SIMILARITY_ERROR
  * METRIC_STRUCTURAL_DISSIMILARITY_ERROR
  * COMPRESSION_ZSTD - https://github.com/facebook/zstd
  * COMPRESSION_WEBP
  * CHANNEL_COMPOSITE_MASK
  * FILTER_CUBIC_SPLINE - "Define the lobes with the -define
    filter:lobes={2,3,4} (reference
    https://imagemagick.org/discourse-server/viewtopic.php?f=2&t=32506)."
  * Imagick now explicitly conflicts with the Gmagick extension.

- Fixes:

  * Correct version check to make RemoveAlphaChannel and
    FlattenAlphaChannel be available when using Imagick with ImageMagick
    version 6.7.8-x
  * Bug 77128 - Imagick::setImageInterpolateMethod() not available on Windows
  * Prevent memory leak when ImagickPixel::__construct called after object
    instantiation.
  * Prevent segfault when ImagickPixel internal constructor not called.
  * Imagick::setResourceLimit support for values larger than 2GB (2^31) on
    32bit platforms.
  * Corrected memory overwrite in Imagick::colorDecisionListImage()
  * Bug 77791 - ImagickKernel::fromMatrix() out of bounds write.
