Change source download method due to upstream limitations

ImageMagick have an uncommon source distribution model:

New releases appears firstly at imagemagick.org, but this
website does not provide tarballs for all previous versions
(only a tarball for the latest version is available from
there).

A tarball archive of previous versions can be found at the
official github website, but strangely, the tarball of the
current version appears there only after a certain lagging
period.

Using git clone as the source instead of the tarball allows to:
 - provide a new release as soon as possible
 - allows users to build the package with the older version if
   a new version is released upstream and the AUR package still
   had not the time to update the PKGBUILD
 - offers the possibility to lock-up the package at a certain
   version whithout any modification in this PKGBUILD (for
   example, if some build problem occurs with a newer version).
