self is included in a target type set.
When neverallow checking was refactored in commit 9e6840e, self
was not handled correctly. The assumption was made that self only
appeared by itself as a target type, when it may appear in a list of
types. Because of this, if self appears in a target type set of a
neverallow, the other types in the type set are not checked.
Example:
allow TYPE1 TYPE2:CLASS1 { PERM1 };
neverallow TYPE1 {TYPE2 self}:CLASS1 { PERM1 };
The old assertion checking would not find a violation in the rules
above because the target type TYPE2 would be ignored.
This fix will cause all of the types in a target list that includes
self to be checked.
