Set the head table checkSumAdjustment to zero

...before calculating the head table checksum. Per the head table specification: > checkSumAdjustment: To compute set it to 0, calculate the checksum for the 'head' table and put it in the table directory, sum the entire font as a uint32_t, then store 0xB1B0AFBA - sum. (The checksum for the 'head' table will be wrong as a result. That is OK; do not reset it.) ref #123
