test46: Add test to write eeprom, with calibration data taken from sdbfs/calib. 

This test is used to fix problem found in batch of 100 boards from Creotech (2014).
It is used by the script tests/fix_creothech_batch_2014.sh

test46: Write IPMI information and calibration data to FMC EEPROM.
This is done using gensdbfs tool.
Serial number is taken from a text file (../serial.txt).
Calibration data are taken from a binary file (sdbfs/calib).
Note: Requires test00.py to run first to load the gateware!
Is meant to run with fix_creotech_batch_2014.sh
