vyos.utils: T7122: fix IPv6 support in check_port_availability()
Commit 4523e9c897b3 ("wireguard: T3763: Added check for listening port
availability") added a function to check if a port is free to use or already
occupied by a different running service. This has been done by trying to bind a
socket to said given port.
Unfortunately there is no support for IPv6 address-fdamily in both
socketserver.TCPServer or socketserver.UDPServer. This must be done manually by
deriving TCPServer and setting self.address_family for IPv6.
The new implementation gets rid of both TCPServer and UDPServer and replaces it
with a simple socket binding to a given IPv4/IPv6 address or any interface/
address if unspecified.
In addition build time tests are added for the function to check for proper
behavior during build time of vyos-1x.
