ramdisk: Disable secure ADB on recovery

- For some odd reason, when we boot into Lineage recovery, ADB shows an unauthorized state regardless of any actions taken. By disabling secure ADB, it starts to work fine.
- Additionally, ADB sideload does not work as it still shows recovery instead of sideload. This is mostly due to the old FunctionFS implementation in this 3.18 kernel.
