[PATCH 4/4] ls: Fix showing links to directories

[Sascha Hauer <s.hauer@pengutronix.de>]

With links to directories we have to do some adjustments in the
printout. In ls_one we have to use lstat() because we want to
show informations about the file or link. When determing if it's
a file or directory that we show we have to use stat() instead.
