Subject: [PATCH] Allow BLKIOMIN and BLKALIGNOFF ioctls to the super device in
fastbootd.
These ioctls are similar to BLKGETSIZE64; they return benign information
about the partition's alignment, and are used by liblp to optimally
align dynamic partition extents.
The system_block_device is included here because on retrofit devices,
the "super" partition is mapped to the system partition.
Bug: 116802789
Test: fastboot flashall
