[thd72] Fix initialization of skip byte in clone mode driver. #697

Paul Cummings programmed his TH-D72 with Chirp's clone mode driver and now his
radio will not scan past channel 136. When recalled on the radio, the lockout
value for memory 137+ is corrupt.

Upon examination of his img file, unknown1 was 0xFE for channels greater than
136. On my non-corrupt radio, unknown1 is always 0x00. Based on the "random
characters", it appears the D72 reads the full byte (unknown1 + skip) to
evaluate lockout. This patch modified Chirp to read the full byte.
