Add trampoline init script to ARM host image

This init script is used by secondary storage
to set the initial state of the environment
partition on the eMMC.  This is useful for two
purposes: setting the boot order so secondary
storage is always booted first, and setting
the ethaddr to the value that is stored on the
secondary storage.
