BUG: Make iscomplexobj compatible with custom dtypes again
This change makes iscomplexobj compatible with custom array types
using custom dtypes, that are not fully compatible to Numpys dtypes,
which can nevertheless be coerced to a numpy array with asarray
again, as has been the behaviour before PR #7936.
Fixes #8601
