Consider to use python -c to simplify the manipulation. #Closed

Fixing testing is required. Code improvement is not necessary but highly suggested.

probably I can remove last byte masking as it is already done for the MAC in DB

- What I did
Updated syncd init script to pass MAC from EEPROM to SAI for Mellanox platforms. Interfaces will be created with this MAC
- How I did it
updated syncd init script (syncd_init_common.sh)
- How to verify it
Start SONiC and make sure MACs on Interfaces are similar to one returned by command
od -vt x1 -An /sys/bus/i2c/devices/8-0051/eeprom | xargs printf "0x%s " | xargs printf "%02x:" | awk 'BEGIN { FS=":"; i=8+1+2+1} {while(i<NF) {type=$i; len=("0x"$(i+1));if(type!="24") {i=i+2+len} else {print substr($0, (i+1)3+1, len3-1); break}}}'
some bits in last byte may differ
