When using an initramfs, the default for poky-tiny, the kernel can't
automatically mount devtmpfs. Ensure it is mounted. This eliminates the
need to create the ptmx device.

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.
