python/sepolgen: fix access vector initialization

In access module, in AccessVector.__init__() method, when init_list is
not None, the access vector is initialized by from_list() method.
However, this method does not assign attributes self.audit_msgs,
self.type, and self.data. Fix this by assigning these attributes in
__init__() method.
