dumpheader: Add default serial number in the header

Whenever the serialNo is empty, use a default serial
number (all zeroes) so that scripts/apps that decode
the dump header would not throw errors.

Use fetch_serial_number() so that default serialNo
gets populated whenever the serialNo is empty.

Verified that the default serial number is utilized.
