[OE-core] [meta][PATCH] ltp: fix shmctl01 failure when executed.

[Hongzhi.Song]

schmctl01 fails with following error:
[shmctl01    5  TFAIL  :  shmctl01.c:171: shmctl01 call failed - errno =
22 : Invalid argument]

Backport the patch from upstream can fix it.

+Subject: [PATCH] shmctl01: don't use hardcoded index == 0 for SHM_STAT test
+
+Test fails on SHM_STAT testcase:
+   shmctl01    5  TFAIL  :  shmctl01.c:173: shmctl01 call failed
+                            errno = 22 : Invalid argument
+   shmctl(0, SHM_STAT, 0x601060)           = -EINVAL
+
+since following commit:
+   commit 99db46ea292780cd978d56932d9445b1e8bdafe8
+   Author: Manfred Spraul <manfred at colorfullife.com>
+   Date:   Tue May 14 15:46:36 2019 -0700
+     ipc: do cyclic id allocation for the ipc object.
+
+Don't rely on index 0 being always available, but instead
+use (maximum) index returned by SHM_INFO.
