avutil/timecode: Use a 64bit framenum internally
Fixes: negation of -2147483648 cannot be represented in type 'int'; cast to an unsigned type to negate this value to itself
Fixes: 68550/clusterfuzz-testcase-minimized-ffmpeg_dem_MXF_fuzzer-6424065930756096
Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/projects/ffmpeg
