phosphor-ipmi-net.socket: adjust BindToDevice

BindToDevice arguments are suppose to be an interface name and
not a systemd dependency target.  See examples from systemd
repository[1].  Adjust the socket file to BindToDevice the template
argument instead of the systemd service name.

The current socket file fails with systemd-v257.4.  This version has
been tested with the current systemd in openbmc (v257.1) and v257.4
at Iae0001d2feecd2a5b699cdc95fe37b1491ba0c38.
