gbmc-dump-ramoops: Add lastrebootcause file
Add a file to /tmp/ to indicate the last reboot is a crash or software reboot/AC power on
Tested:
File is created and shows correct value.
* On BMC reboot or powercycle:
```
root@host-nfd01:~# cat /tmp/lastrebootcause
0
```
* When crash happened:
```
root@host-nfd01:~# echo c > /proc/sysrq-trigger
root@host-nfd01:~# cat /tmp/lastrebootcause
1
```
