busybox: Introduce poky-tiny defconfig override

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.
