common/env_flags.c: Add function to validate a MAC address

Browse Source 
The code that checks if a string has the format of a MAC address has been
moved to a separate function called eth_validate_ethaddr_str().

This has been done to allow other components (such as vsc9953 driver)
to validate a MAC address.
