meta-google: Add new system.conf for gbmc-systemd-config
Add systemd.conf options for watchdog to replace watchdog-conf
```
// interval is 60s by default
interval = 10
watchdog-device = /dev/watchdog
// The value is in pages. They are presently 4KiB each.
// Reset the BMC if it goes below 3MiB
min-memory = 768
```
Tested:
```
$ cat /lib/systemd/system.conf.d/40-system.conf
[Manager]
DefaultMemoryAccounting=yes
RuntimeWatchdogSec=10s
WatchdogDevice=/dev/watchdog
```
