[patch] Implement ISO/IEC TS 18822 C++ File system TS

[Jonathan Wakely]

Another portability fix, to avoid using &stat::st_atime because
st_atime might be a macro, and &stat::st_atim.tv_sec is not valid.

Also POSIX doesn't actually require any particular structure for
timespec, so set the fields explicitly instead of using braces.

Tested powerpc64le-linux and powerpc-aix7, committed to trunk.
