VPD ECC shared library

This commit makes the VPD ECC source into a shared library
and links the shared library with other executables which
are dependant on VPD ECC.

Since the ECC source file is confidential, we need to share the
ECC as a shared library to the IBM Power customers.

Test:
Tested on simics:
1. Corrupted the vpd data.
root@p10bmc:/usr/lib# dd if=/dev/zero of=/sys/bus/i2c/drivers/at24/7-0050/eeprom bs=1 count=2 seek=184
2+0 records in
2+0 records out

root@p10bmc:/usr/lib# ibm-read-vpd --file /sys/bus/i2c/drivers/at24/7-0050/eeprom
ERROR: ECC check did not pass for the Record:VINI

2. VPD Parser parsed successfully for a valid vpd
root@p10bmc:/usr/lib# ibm-read-vpd --file /sys/bus/i2c/drivers/at24/7-0050/eeprom
<no error>

3.ECC Code worked fine with VPD-Manager
root@p10bmc:/usr/lib# vpd-tool -w -O /system/chassis/motherboard/base_op_panel_blyth -R VINI -K PN -V "PN34"
root@p10bmc:/usr/lib# ibm-read-vpd --file /sys/bus/i2c/drivers/at24/7-0050/eeprom
root@p10bmc:/usr/lib#
root@p10bmc:/usr/lib#
root@p10bmc:/usr/lib# vpd-tool -w -O /system/chassis/motherboard/base_op_panel_blyth -R VINI -K PN -V "PN12"
root@p10bmc:/usr/lib# ibm-read-vpd --file /sys/bus/i2c/drivers/at24/7-0050/eeprom
