Remove experimental filesystem splice

In order to be compatible with older versions of GCC that did not have
the experimental filesystem moved over to the standard paths, the code
would splice the experimental code into the std namespace. This is no
longer necessary with yocto 2.6 and the latest versions of GCC.
