avformat/framecrcenc: Don't read after the end of side-data
Nothing guarantees that the size of side data containing a palette
is actually divisible by four (although it should be); but for
big-endian systems, an algorithm is used that presupposed this.
So switch to an algorithm that does not overread: It processes
four bytes at a time, but only if all of them are contained in
the side data.
