update casacore patch

I think they slightly changed the CMakeLists in casacore, this patch should work with the new one - is that ok?

Do we need to collect patches for the differing versions? I guess if you want to switch between a stable release and the development branch, the latter will need frequent updating.

Easiest would be to change all patch application to test if

$package.$

version.patch exists, if not, check if $package.patch exists … apply if found.
