[issue41287] __doc__ attribute is not set in property-derived classes

Sergei Izmailov  added the comment:

class Property(property):
'custom docstring'

print(Property(None, None, None, "hello").__doc__)

This snippet is expected to print "hello" as well (at least it's what comment 
in cpython implementation suggests)
