cmd/ntp: preserve system time in /perm across reboots ( #359 )
...
Why? Reduce the wall time during which the system believes it's 1970.
Makes syslog timestamps more sensible.

ntp: Allow alternative NTP servers as arguments ( #244 )
...
When the gokrazy deployment doesn't have internet access and the network
lacks NTP traffic re-routing to the local time servers, instances may
either have downright wrong clock (e.g. Raspberry Pi with no RTC) or
experience divergence due to drift.
This add the ability to override the default NTP Pool Vendor Zone for
gokrazy with servers supplied as command line arguments.
e.g.
```
"PackageConfig": {
"github.com/gokrazy/gokrazy/cmd/ntp": {
"CommandLineFlags": [
"time1.local",
"time2.local",
"10.1.2.123"
]
}
}
```

ntp: randomly select a pool address every time
...
In particular, only pool 2.gokrazy.pool.ntp.org has IPv6 addresses, so this
fixes setting the time via NTP in IPv6-only environments.
