[vcpkg baseline][osg] Fix build error when building plugin RestHttpDevice

[JackBoosY]

Use unofficial workaroud to fix build error:

/mnt/_work/1/s/buildtrees/osg/src/raph-3.6.4-c5448290ed/src/osgPlugins/RestHttpDevice/server.cpp:35:29: error: ‘error’ is not a member of ‘asio::placeholders’
         asio::placeholders::error));
                             ^~~~~

Fix #11686

This breaks because boost::bind follows asio's completion token protocol while std::bind does not.

@BillyONeal Hmm... do you have any suggestions to fix this issue?
