Throw excpetion when it is not allowed to set time

When it is not allowed to set time depending on the time setting,
previously we only log an error and continue.
Now sdbusplus supports errors on properties, so we can throw exception
on such case.

Tested: Verify in unittest that exception is thrown when it is not
        allowed to set time.
        Verify in BMC that busctl gets the error message when it is not
        allowed to set time.
