Increase recursion limit

When germinate is run with apertis packages as seed it results in below exception,

File "/usr/lib/python3/dist-packages/germinate/germinator.py", line 1224, in _get_dependency_candidates
    if self._allowed_dependency(pkg, candpkg, seed, build_depend):
  File "/usr/lib/python3/dist-packages/germinate/germinator.py", line 1156, in _allowed_dependency
    self._is_pruned(self._di_kernel_versions, depname)):
RecursionError: maximum recursion depth exceeded

To fix this increase the recursion limit to higher value.
