package/gdal: giflib and qhull are mandatory

giflib and qhull are mandatory since the addition of the package in
commit 1e64fa2956171cdc9d6e6c8896b4b589ce573513 and
https://github.com/OSGeo/gdal/commit/cb136fc051341ab99579daae3c8d8246fe918a76

Indeed, as explained in above commit, internal (bundled) libraries will
be used if GDAL_USE_GIF and GDAL_USE_QHULL are set to OFF
