[LTP] [PATCH v1] Add chdir05 test

[LTP] [PATCH v1] Add chdir05 test

[Andrea Cervesato]

From: Andrea Cervesato <andrea.cervesato@suse.com>

This test has been extracted from symlink01 and it verifies that
chdir() is working correctly on symlink() generated files.

This two should go to chdir01.c and possibly chdir01 should be split
into positive cases and negative cases when you are at it.

This is already in chdir01.c

Hi!

this patch can be ignored due to code duplication.
