ftw.3: Reorganize the page to give primacy to nftw()

nftw() is the better API, and POSIX.1-2008 marks ftw() obsolete.

Signed-off-by: Michael Kerrisk <mtk.manpages@gmail.com>

ftw.3: ftw() and nftw() differ for the non-stat-able symlink case

The POSIX specification of ftw() says that an un-stat-able
symlink may yield either FTW_NS or FTW_SL. The specification
of nftw() does not carry this statement.
