debian: Move ovs-flowviz to openvswitch-common.

The ovs-flowviz executable Python script is expected to be
executed by the end user.

Surveying where current executable binaries are installed for the
package, the placement of ovs-flowviz in python3-openvswitch
is unexpected to me, other client binaries are shipped inside the
openvswitch-common package.

To me, the python3-openvswitch package represents a library
dependency, which you would install to get the Python ovs module
for your Python application to consume.

This is also the current choice of placement for the downstream
Debian / Ubuntu package [0].

Consequently this patch proposes to move ovs-flowviz and its
manual page to openvswitch-common.

The Python dependencies are added as recommended dependencies,
which will retain good interactive UX, and at the same time allow
non-interactive users to opt out.
