Subject: busybox: add initrd variant

Add a busybox variant that inherits almost all of its support from
the core busybox recipe, but adds configuration values that are
appropriate to be used in an initrd.

In particular:

  - we build busybox statically
  - we enable runlevel and init functionality
  - mdev is always enabled
  - applet install support is enabled
