commands: add new uptime command
We have a time command to record the delta of get_time_ns() to time
command execution, but have no command to just print get_time_ns().
Such a command can be useful to debug clocksources or to verify that a
system is still running and hasn't been reset by a yet unhandled
watchdog in-between.
Make development a bit easier by providing a new uptime command.
