[torquedev] Compilation warning

[Simon Toth]

Looking at the code, I don't know what to change. Strlen cannot return
negative value and ptr[0] definitely is not bellow array bounds. Maybe
its about "path_checkpoint - 1".

cc1: warnings being treated as errors
checkpoint.c: In function 'replace_checkpoint_path':
checkpoint.c:409: error: array subscript is below array bounds
