[Buildroot] [git commit branch/2019.02.x] package/imagemagick: explicitly disable opencl

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=f31498587a4b0b6d7f8efab2b63d8f8041bab091
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2019.02.x

Some packages installs libOpenCL without declaring
BR2_PACKAGE_PROVIDES_LIBOPENCL (e.g.  imx-gpu-viv).  ImageMagick will detect
the library and will require libtool.  Since libtool is not in dependencies,
build might fail.

To prevent that situation, explicitly disable opencl support for target and host.
