meta-openembedded and poky: subtree updates

Squash of the following due to dependencies among them
and OpenBMC changes:

meta-openembedded: subtree update:d0748372d2..9201611135
meta-openembedded: subtree update:9201611135..17fd382f34
poky: subtree update:9052e5b32a..2e11d97b6c
poky: subtree update:2e11d97b6c..a8544811d7

The change log was too large for the jenkins plugin
to handle therefore it has been removed. Here is
the first and last commit of each subtree:

+Subject: [PATCH] realpath.c: Remove trailing slashes
+
+Linux system's realpath() remove trailing slashes, but pseudo's doesn't, need
+make them identical.
+
+E.g., the following code (rel.c) prints '/tmp' with system's realpath, but
+pseudo's realpath prints '/tmp/':
+
+    #include <stdio.h>
+    #include <limits.h>
+    #include <stdlib.h>
+
+    int main() {
+        char out[PATH_MAX];
+        printf("%s\n", realpath("/tmp/", out));
+        return 0;
+    }
+
+$ bitbake base-passwd -cdevshell # For pseudo env
+$ gcc rel.c
+$ ./a.out
+/tmp/ (but should be /tmp)
+
+This patch fixes the problem.
