doc/filters: Change rdiv (vf_convolution) documentation to reflect actual behavior

The documentation correctly states that the rdiv is a multiplier but incorrectly states the default behavior is to multiply by the sum of all matrix elements - it multiplies by 1/sum.

This changes the documentation to match the code.

Address trac #10889
