[LTP] [PATCH] Convert chdir01 to the new API

Hi,

chdir02.c tests chdir("/"); and chdir("/tmp"). Not sure whether full path is
more coverage than relative path from chdir01.c.
If we consider these useful, we can just add it into chdir01.c.

Although it looks a bit strange to chroot into root, I'd use just that and avoid
/tmp (it breaks at least for Android with no good reason).

It might makes sense to use .all_filesystems = 1.

Got the same problem on 5.8.0 (on all filesystems).
