[meta-oe] [PATCH V2] librcf: fix a clang compiling issue

[liu.ming50@gmail.com]

From: Ming Liu <peter.x.liu@external.atlascopco.com>

A error was observed with clang compiler, as follows:
| src/RCF/RCF.cpp:49:
| src/RCF/ClientStub.cpp:28:
| include/RCF/Future.hpp:49:26: error: 'enrol' is a private member of 'RCF::ClientStub'

it can be fixed by declaring Future as a friend class of ClientStub.
