Mans Rullgard 2c99aa48d7 lavf: fix signed overflow in avformat_find_stream_info() ...

On the first iteration through this code, last_dts is always
INT64_MIN (AV_NOPTS_VALUE) and the subtraction overflows in
an invalid manner.  Although the result is only used if the
input values are valid, performing the subtraction is still
not allowed in a strict environment.
