feat(libSceNpEntitlementAccess): report signed out for entitlement info lists

The unified and service entitlement info list requests and polls threw.
They now return SCE_NP_ERROR_SIGNED_OUT, like the consume requests in
the same library. Their signatures are unknown, so they stay declared
without parameters.

PPSA15657 calls the unified request during start-up and continues past
the error.

 ### Unknown function info
 
 - [sceNpEntitlementAccessGetEntitlementKey](../../core/libs/prx/libSceNpEntitlementAccess/Export.cpp) - the three-argument signature, 16-byte key and errors `0x817D0002`/`0x817D0007` follow [KytyPS5](https://github.com/KytyPS5/KytyPS5/blob/main/src/libs/libNet.cpp); PPSA01521 passes a service label, entitlement label and output pointer. Only the no-key path is implemented: local entitlement labels carry no keys, and the output is untouched on failure. Console error precedence and key provisioning are unverified
+- [sceNpEntitlementAccess{Request,Poll}{Unified,Service}EntitlementInfoList](../../core/libs/prx/libSceNpEntitlementAccess/Export.cpp) - signatures unknown; no reference implements them, so they are declared without parameters. Like the consume requests in the same library, they report the signed-out NP state with `SCE_NP_ERROR_SIGNED_OUT` (`0x80550006`) and write nothing. PPSA15657 calls the unified request during start-up and continues past the error. Whether the console fails at the request or at the poll when signed out is unverified
 - [sceRudpGetStatus](../../core/libs/prx/libSceRudp/Export.cpp) - PPSA01521 passes an output pointer and byte count `0xF8`; the status layout, size rules and error behavior are unknown. The export throws without writing output, including after initialization. [shadPS4](https://github.com/shadps4-emu/shadPS4/blob/main/src/core/libraries/rudp/rudp.cpp) declares it without arguments and returns success without writing status
 - [sceHttpSetCookieEnabled](../../core/libs/prx/libSceHttp/Export.cpp) - the two-argument signature and 0/1 enable values follow [VitaSDK](https://github.com/vitasdk/vita-headers/blob/master/include/psp2/net/http.h) and [shadPS4](https://github.com/shadps4-emu/shadPS4/blob/main/src/core/libraries/network/http.cpp); PPSA01521 passes 0 to disable cookies. Disabling succeeds because the offline HTTP backend has no cookie engine; enabling throws. Invalid enable values use the same error as `sceHttpSetInflateGZIPEnabled`. Like the existing offline HTTP setters, the handle is not validated; requests still fail with the network error. Console behavior is unverified
