Update to 4.7.9:

SIP v4.7.9 has been released.

This is a bug fix release needed to build PyKDE v3.16.2.

SIP v4.7.8 has been released.

* Added the /Deprecated/ class and function annotation (based on
a patch from Lorenzo Berni).
* Templates now support instance variables and enums.
* A Python int object can now be used whenever an enum is expected
without needing to explicitly cast it using the enum's constructor.
The /Constrained/ argument annotation can be used to suppress this
behaviour.
* typedef type names are now used in string representations of
types (e.g. in the names of mapped types) to reflect what the
programmer sees rather than what the compiler sees. The /NoTypeName/
typedef annotation can be used to suppress this behaviour.
