fix symlinks on symlink-capable os but non-symlink-capable filesystem

1. write a symlink directly as a symlink (currently it's being written as a
   file, and only then switched to a symlink by set_flags); note that writing
   as a symlink already makes sure that the fs supports symlinks.
2. set_flags should only switch a file to a symlink on a symlink-capable fs.
