Revert "build: missed gnuradio-uhd in static libs build."

This reverts commit 45f12cf0031cdf594dff8a9bfc7db395cd39ca37.
build: better support for static libs.

Now builds shared libraries with ControlPort (if ControlPort is enableed). Static libs still without ControlPort.

Added proper Option and output message in cmake for Static Libs on/off.
filter: fixed relative_rate setup in pfb_channelizer.

The channelizer takes in data already decimated by N channels, generally througha stream_to_streams block on the input ports. This already changes the relative rate, so 1 input sample per port equals M samples on the output channel where M is the oversampling rate.
