lavu/error: fix sign error in av_sterror() error code
The value returned by strerror_r may be positive depending on the system,
so it is necessary to use AVERROR() in order to get a negative
number. This way the successive negative check will not fail, and the
function will print a meaningful error message on the buffer.
