sandbox: keep time offset when resetting
The UEFI Self Certification Test (SCT) checks the SetTime() service with
the following steps:
* set date
* reset
* check date matches
To be compliant the sandbox should keep the offset to the host RTC during
resets. The implementation uses the environment variable
UBOOT_SB_TIME_OFFSET to persist the offset.
