[LTP] [PATCH v4 1/2] open: remove O_DIRECTORY case (move to fstat test)

[Jinseok Kim <always.starving0@gmail.com>]

The O_DIRECTORY test case was mostly verifying fstat() behavior on an
existing directory rather than testing any specific open() behavior.

Following review suggestion, remove it from open01.c. A separate fstat
test will be added in a follow-up patch to cover file type checks
(S_ISDIR, etc.) more comprehensively.

 /*
  * DESCRIPTION
  *	Open a file with oflag = O_CREAT set, does it set the sticky bit off?
- *	Open a dir with O_DIRECTORY, does it set the S_IFDIR bit on?
  *
  * ALGORITHM
  *	1. open a new file with O_CREAT, fstat.st_mode should not have the
  *	   01000 bit on. In Linux, the save text bit is *NOT* cleared.
- *	2. open a new dir with O_DIRECTORY, fstat.st_mode should have the
- *	   040000 bit on.
