meta-phosphor: static-norootfs-init: support factory-reset
Add support to check the uboot environment for 'factory-reset' as
programmed by phosphor-bmc-code-mgmt's FactoryReset interface.
Tested:
Ran the following and observed the file missing after reboot:
```
touch /var/DELETE_THIS_FILE
busctl call xyz.openbmc_project.Software.BMC.Updater \
/xyz/openbmc_project/software \
xyz.openbmc_project.Common.FactoryReset Reset
reboot
```
During the reboot observed the following message, along with ubiformat
messages:
```
Formatting persistent volume:
factory-reset
```
