imx-uuc: new package

This package provides the Universal Adapter user-space utility that is
used to receive commands from the Manufacturing Tool using the Freescale
UTP Protocol.

It requires a Freescale/NXP kernels whose configuration contains the
CONFIG_FSL_UTP option.

The /fat file is provided as a bootargs to the g_mass_storage driver
from U-Boot, see:
http://git.freescale.com/git/cgit.cgi/imx/uboot-imx.git/tree/include/
configs/mx6sabre_common.h?h=imx_v2015.04_3.14.52_1.1.0_ga#n116

Init scripts are provided so that the tool starts automatically at
bootup.

Tested on Nitrogen6_MAX + MFGTools.

[Thomas:
 - test return value from start-stop⁻daemon in init script, and
   reindent the init script
 - fix dependency of the comment
 - rewrap Config.in help text.]
