vulkan: change to clamp to edge rather than clamp to border

Browse source 
clamp-to-border will return the border color which is typically black,
white or transparent.  When linear filtering the edge pixels will
typeically be combined with the border color which is not typically what
we want.  Especially when color converting, this removes a green box
around the edge when converting YUV->RGB.
