lavc/vc1dsp: fix overflow in R-V V inv_trans_8
The last set of additions/subtractions can break the 16-bit limit, and
require 17 bits of precision. This uses widening adds accordingly to fix
the MSS2 FATE tests.
The problem potentially also affects inv_trans_4 with a very low
probability, but this is not reproducible under FATE.
