Rewrite cap_integrity test for Fiasco.OC (fix #161)

By commit d287b9d893 the Native_capability
class changed fundamentally in the Fiasco.OC platform code of Genode. Thereby
the cap_integrity test got incompatible with it. This commit introduces a
separate test implementation for Fiasco.OC that does semantically the same
like the old test. Please refer to issue #161.
