libstdc++: Do not optimize away storing pathname if it's needed
libstdc++-v3/ChangeLog: * src/c++17/fs_dir.cc (_Dir::_Dir) [!_GLIBCXX_HAVE_OPENAT]: Always store pathname if we don't have openat or unlinkat, because the full path is needed to open sub-directories and remove entries. (cherry picked from commit 835b19936bf30d693783bfa39145a4ce243bbd7c)
