ltp: Fix containers/userns05 failure for lib32

Backport a patch to fix userns05 case:
<<<test_output>>>
user_namespace5 1 TFAIL : userns05.c:95: userns:parent should be not equal to cpid2
user_namespace5 1 TFAIL : userns05.c:95: userns:parent should be not equal to cpid2
user_namespace5 0 TINFO : Child process returned TPASS
user_namespace5 0 TINFO : Child process returned TPASS
user_namespace5 0 TINFO : Child process returned TFAIL
incrementing stop

Rename the previous patch to add a number prefix

+Subject: [PATCH] containers/userns05: use unsigned int for ns id
+
+The kernel defines it as 'unsigned int' in 'struct ns_common'
+and formats it as
+
+  snprintf(buf, size, "%s:[%u]", ns_ops->name, ns->inum);
+
+This change makes the test work on 32bit systems where LONG_MAX
+is smaller than UINT_MAX.
