Force ipv4 in gpsd.socket on Jetson Nano

[mattdibi]

Disabled gpsd-related services

Description of the solution adopted:

Currently on the Jetson Nano profile systemctl reports a failure with:

jetson@jetson-nano:~$ systemctl list-units --failed
UNIT LOAD ACTIVE SUB DESCRIPTION
● gpsd.socket loaded failed failed GPS (Global Positioning System) Daemon Sockets
LOAD = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB = The low-level unit activation state, values depend on unit type.
1 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.

because:

jetson@jetson-nano:~$ sudo systemctl status gpsd.socket
● gpsd.socket - GPS (Global Positioning System) Daemon Sockets
Loaded: loaded (/lib/systemd/system/gpsd.socket; enabled; vendor preset: enabled)
Active: failed (Result: resources)
Listen: /var/run/gpsd.sock (Stream)

mar 16 11:56:17 jetson-nano systemd[1]: Failed to listen on GPS (Global Positioning System) Daemon Sockets.

With this PR we ensure both gpsd.service and gpsd.socket are disabled on Kura installation.

Maybe try to change the service definition to enable only ipv4, disabling ipv6. Maybe this solves

@MMaiero Updated installer with

#force gpsd.socket to use only ipv4
sed -i "s/\(ListenStream=\[::1\]\)/# \1/g" /lib/systemd/system/gpsd.socket

So that we have /lib/systemd/system/gpsd.socket:

[Unit]
Description=GPS (Global Positioning System) Daemon Sockets

[Socket]
ListenStream=/var/run/gpsd.sock
# ListenStream=[::1]:2947
ListenStream=127.0.0.1:2947
SocketMode=0600

[Install]
WantedBy=sockets.target

It looks happy now:

jetson@jetson-nano:~$ systemctl list-units --failed
0 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.

jetson@jetson-nano:~$ systemctl status gpsd.socket
Failed to dump process list, ignoring: No such file or directory

That's exactly what I've meant. Maybe you'll also need to open the firewall for pot 2947 to lo

@MMaiero It didn't look like it was strictly needed by I added it anyway.
