meta-yocto: Rename to meta-poky to better match its purpose

"poky" is the reference distribution for the Yocto Project. This renames
the layer within the meta-yocto repository to meta-poky, better matching
what that layer contains.

A layer.conf file is left behind as this is the only way which allows
existing builds to migrate safely to the new name. It will be removed
at some future point.

This change requires the corresponding OE-Core change to handle the
migration and the changes to the infrastructure to support this.

+# Poky-tiny is intended to define a tiny Linux system comprised of a
+# Linux kernel tailored to support each specific MACHINE and busybox.
+# Poky-tiny sets some basic policy to ensure a usable system while still
+# keeping the rootfs and kernel image as small as possible.
+#
+# The policies defined are intended to meet the following goals:
+# o Serial consoles only (no framebuffer or VGA console)
+# o Basic support for IPV4 networking
+# o Single user ash shell
+# o Static images (no support for adding packages or libraries later)
+# o Read-only or RAMFS root filesystem
+# o Combined Linux kernel + rootfs in under 4MB
+# o Allow the user to select between eglibc or uclibc with the TCLIBC variable
+#
+# This is currently a partial definition, the following tasks remain:
+# [ ] Integrate linux-yocto-tiny ktype into linux-yocto
+# [ ] Define linux-yocto-tiny configs for all supported BSPs
+# [ ] Drop ldconfig from the installation
+# [ ] Modify the runqemu scripts to work with ext2 parameter:
+#     runqemu qemux86 qemuparams="-nographic" bootparams="console=ttyS0,115200 root=0800"
+# [ ] Modify busybox to allow for DISTRO_FEATURES-like confiruration
