[LTP] [PATCH v2] syscalls/setgid: Update to new API

[Zhao Gongyi <zhaogongyi@huawei.com>]

For those:
	testcases/kernel/syscalls/setgid/setgid01.c
	testcases/kernel/syscalls/setgid/setgid02.c
	testcases/kernel/syscalls/setgid/setgid03.c

Signed-off-by: Zhao Gongyi <zhaogongyi@huawei.com>
---
v1->v2:
	1)use TST_EXP_PASS/TST_EXP_FAIL to simplify the test code
	2)add discription to setgid01.c
	3)remove gid check for setgid03.c
