vf_lut: add plane validity check in draw_slice()
...
The value for inpic->data[plane] with plane >=4 is undefined, and it
will contain in general random data. This change adds a check for
exiting the loop when plane reaches the value 4.
Fix crash (occurring for example with: format=rgba,lut).

vf_lut: fix draw_slice() in case of non packed image data for packed RGB
...
The previous code was erroneously assuming that the linesize was
equivalent to width*pixel_step, which is not always true.
