Optimize Neon vertical Wiener convolve for 5-tap filters

Wiener convolution filters can be either 5 or 7 taps. The current Neon
implementation pads 5-tap filters with zeros to treat them as 7-tap
filters. This patch adds a Neon path specialised for 5-tap vertical
Wiener filters, avoiding the redundant work of using the 7-tap path
with a 5-tap filter.
