part 2/2 of fixing Altivec-accelerated H264 luma inloop filter

In h264_deblock_q1, the result of the deblock needs to be kept to
be used in future deblocks, so return this value now.

Also change the sign of tc0 vector: It is really a signed value, so
treat it as such until after the >=0 check;...

Use a faster way to compute 255-val: Instead of creating a vector of
all 255s, and then doing the subtraction, nor of the vector with itself: saves
one instruction and a register.

some samples aren't decoded correctly such as
( http://www.pennfans.net/files/videos/Penn&Teller.on.The.View.mp4 )
with current Altivec implementation of loopfilter, while others are fine.
Let's disable it until we iron this bug out.
