Yan Wang a48625d7ff libs: filter: set all color balance values
When set multiple settings of color balance like hue, saturation,
brightness and contrast for vaapipostproc, they should be set as
parameters of color balance filter, at the same color balance
filter calling.

Otherwise, multiple color balance filter calling will cause
previous setting get reset by the last calling with default value.

Fixes #182.
