stat-time, timespec: support use in C++

[Bruno Haible]

Trivial change, to make these modules usable in C++ mode.


2017-03-17  Bruno Haible  <br...@clisp.org>

        stat-time, timespec: Support use of the header files in C++ mode.
        * lib/stat-time.h: Add "C" linkage declaration.
        * lib/timespec.h: Likewise.
