Chirantan Ekbote d8447077f0 devices: fs: Fix linkat impl ... Using AT_EMPTY_PATH with linkat requires the caller to have CAP_DAC_READ_SEARCH in the init user namespace. Since the fs device isn't going to have this when run in a sandbox, switch to using /proc/self/fd with AT_SYMLINK_FOLLOW instead, which is documented in the manpage as an alternative to AT_EMPTY_PATH.
