policyrep.pyi: Update enum annotations.

Update Enum member annotation to address mypy issues like the following:

setools/policyrep.pyi:57: error: Detected enum "setools.policyrep.PolicyEnum"
in a type stub with zero members. There is a chance this is due to a recent
change in the semantics of enum membership. If so, use `member = value` to mark
an enum member, instead of `member: type`  [misc]
    class PolicyEnum(enum.Enum):
    ^
setools/policyrep.pyi:57: note: See https://typing.readthedocs.io/en/latest/spec/enums.html#defining-members
setools/policyrep.pyi:117: error: Enum members must be left unannotated  [misc]
        typebounds: int = ...
        ^
