uhd: Added an operator/ for (fs_path, size_t)

This is useful when constructing property tree paths.
With this path, the following code would be valid:

size_t mb_index = 0;
fs_path mb_root = "/mboards";
mb_root = mb_root / mb_index;

This is a shortcut for the (in UHD very common)

mb_root = mb_root / boost::lexical_cast<std::string(mb_index);
