Allow bind to privileged ports

[ABredhauer]

Im adding the Ps4 integration to HA and this requires HA to bind to port 987 which is not allowed when not running as root. In order to get around this I had to ssh to the container and run
setcap 'cap_net_bind_service=+ep' /usr/local/bin/python3.9

This won't survive container upgrades so is it possible to add this into the run script?
