casacore: Remove Python 2 patch and add #1350 fix

Since we don't install the Python 2 bindings (called "python") anymore,
it is safe to remove patches to that part of the code.

Replace the old patch with a fix to the Dysco tests which was recently
added to the development version in casacore/casacore#1350. This should
be removed when we move to the next casacore release.
