build_library/disk_util: Switch default ext4 inode size to 256 bytes

Browse Source 
Inode sizes smaller than 256:
- don't support extended metadata (nanosecond timestamp resolution)
- cannot handle dates beyond 2038
- are deprecated

Change the default from 128 to 256. There is no way to apply this change on a
mounted filesystem so this change will only apply to new deployments.
