Re-enable support for locking the bootloader on custom rom

[Tecol87]

In the past One Plus allowed to lock the bootloader for custom ROMs. This is a important security feature! Lately some updates removed this feature [0, 1] for a lot of devices.
Please restore this functionality!

This has nothing to do with kernel sources.
