Fixes [YOCTO #2382]
Without /dev/ptmx, ssh logins fail with:
"PTY allocation request failed on channel 0"
As the kernel support already exists in the linux-yocto-tiny kernel,
create the /dev/ptmx device in tiny-init so it works as intended.

Currently poky-tiny images will boot and run /bin/sh, which results in
error messages to the console about being unable to open the tty and job
control being disabled.
The shell must be session leader to open the tty, and the tty must not
be /dev/console (it should be a vt or a physical tty like ttyS0), the
tty is required for job control (handling signals, etc.).
The goals of poky-tiny are to be an initial starting point from which to
build a distribution that does what you want, and NOTHING more.
This patch results in a system that boots with the virtual filesystems
mounted, the local network interface up, and a shell with job control
running, and a hook (/etc/rc.local) for easy customization. Nothing
else.
Enabling the basic busybox init, including the ability to give the
controlling console to commands starting with a dash in inittab results
in a 5664 byte delta (compared with 2560 bytes for enabling setsid and
cttyhack). Note that the help in busybox suggests the cttyhack may be
more reliable than the init support for handing over the controlling
terminal.
So the difference between using a standard init and just enabling the
two options is about 3k, but enabling setsid and cttyhack may enable
others to things besides what I am looking to do. Enabling init in both
DISTRO_FEATURES and busybox is fairly trivial to do, so I think it's
better to leave that as something to add if needed, rather than
something to remove, as that is more consistent with the goals of
poky-tiny.
Thanks to Tim Bird for his suggestion to include support for rc.local by
default.

When building very small systems, it can be useful to spawn a shell from
a simple init script, rather than a full System V Init process. This
requires the shell be the session leader and be able to open the
controlling terminal if it is to have job control.
Create a busybox bbappend in meta-yocto with a poky-tiny/defconfig.
This adds SETSID and CTTYHACK for poky-tiny on top of the oe-core
defconfig.

OE-core now uses the OpenEmbedded logo for the psplash image; override
this and use the Yocto Project image as we did previously.

Using FILESEXTRAPATHS is cleaner than the old FILESPATH-based method, and
as meta-intel layers are using FILESEXTRAPATHS their formfactor bbappends
will now work. In addition I have used FILESEXTRAPATHS_prepend which is
not absolutely necessary, but provides a good working example in case it
is copied by other layers that are intended to be used on top of it.
