Fix format_mac_address function in parse_mac.cc

Apparently the stream manipulator `std::setw` applies only to the next string written to the stream. Hence the function `format_mac_address` in parse_mac.cc only formatted the first pair of hexadecimal digits correctly. This went unnoticed until now because it only makes a difference for numbers below 0x10.
