[LTP] [PATCH v3 0/3] increase pipe2 coverage

[Yang Xu]

Fixes:#625
v2->v3:
Add pipe2_02.c and  pipe2_03.c test.

Noticed that:
Cases use SAFE_PIPE2 macro(it is in review[1]).

Also, laniel has writed test case for pipe2 O_NONBLOCK flag, so I only
cover O_CLOEXEC and O_DIRECT flag.

Yang Xu (3):
  syscalls/pipe2_01: convert into new API
  syscalls/pipe2_02: Add new test for pipe2 O_CLOEXEC flag
  syscalls/pipe2_03: Add new test for pipe2 O_DIRECT flag
