utils: add script ssh-deploy.sh

[DavHau]

This script uses ssh to copy a custom HDZGOGGLE binary to the goggles and replace the running process with it.

This allows for rapid testing of changes, as one doesn't have to put the file on a sdcard each time.

example usage:

Usage: ./utilities/ssh-deploy.sh <host> <HDZGOGGLE_binary>

It stops the running HDZGOGGLE process, uploads the new binary to /tmp and launches it.

The goggle fs remains unmodified and after a reboot everything is back to normal.

don't forget that you can utilize /root/.ssh/authorized_keys so you don't need to type in your password each time.

Great util!

I run into an issue with WiFi connection becoming stale so I can't ssh into it (including running the sh script again).

I have a fix in page_wifi.c:page_wifi_post_bootup_action() to force
page_wifi_bootup_pending

flag to be false if
page_wifi_get_real_address()

returns non-null.
That is, if there's already WiFi connection, then force the flag to false to force restarting WiFi app.

I also change /dev/null to /tmp/HDZGOGGLE.log in case I want log for HDZGOGGLE
