avformat/evcdec: Avoid nonsense casts
...
For uint8_t buf[EVC_NALU_LENGTH_PREFIX_SIZE], &buf still points
to the beginning of buf, but it is of type "pointer to array of
EVC_NALU_LENGTH_PREFIX_SIZE uint8_t" (i.e. pointer arithmetic
would operate on blocks of size EVC_NALU_LENGTH_PREFIX_SIZE).
This is of course a different type than uint8_t*, which is why
there have been casts in evc_read_packet(). But these are unnecessary
if one justs removes the unnecessary address-of operator.

avformat/evcdec: use an unsigned type for nalu_size
...
But ensure the value returned by evc_read_nal_unit_length() fits in an int.
Should prevent integer overflows later in the code.

It's not necessary. Setting AVStream.avg_frame_rate is enough.
