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] xattr: adjust for attr 2.4.48 release
+
+Latest versions of attr have removed the xattr.h header,
+with the rationale that libc is providing the same wrappers.
+
+attr/attributes.h is providing the ENOATTR definition.
+
