[LTP] [PATCH v8 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.
