avutil/mathematics: Fix undefined negation in av_compare_ts()

Fixes: negation of -9223372036854775808 cannot be represented in type 'int64_t' (aka 'long'); cast to an unsigned type to negate this value to itself
Fixes: 29437/clusterfuzz-testcase-minimized-ffmpeg_dem_MOV_fuzzer-4748510022991872
Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/projects/ffmpeg
