avfilter/vf_v360: fix several problems with 'perspective' output
The image center wasn't preserved, the output image was mirror reversed,
and rotations were made around wrong axes.
I did also remove the vector normalization, because it's sure that the vector
is already normalized if it's calculated from sin() and cos() terms.
