patch for extending an input format

The original "cvequalizehist" element only accepts a grayscale image as an
input.
However, the most images users want to handle are colored images.
I extended its input format from grayscale to colored.
Please find the attached patch.

This patch was modified from d4703fa8806cf7d9cc778fb43370daebb37e70cd,
and you can check it using the following command.

gst-launch-1.0 videotestsrc pattern=13 ! tee name=t t. ! queue ! videoconvert !
xvimagesink t. ! queue ! cvequalizehist ! videoconvert ! xvimagesink

Thank you.
