[yocto] [meta-oic][PATCH] Hotfix: Include functional header for g++-7.1.0

[Philippe Coval]

Reason is described in gcc7 porting notes:
"Several C++ Standard Library headers
have been changed to no longer include the <functional> header.
As such, C++ programs that used components defined in <functional>
without explicitly including that header will no longer compile."

It was tested on yocto poky master on iotivity-1.2.1 (and later)
