If users choose to build OpenWrt with btrfs included and want to use a btrfs RAID for overlay/extroot, then devices need to be scanned *before* mounting overlay/extroot. If not, btrfs won't find all RAID drives and fail to mount. This commit: - creates a duplicate (symlink) of the btrfs scan script so that it runs both before and after overlay/extroot mount, - changes the scan command to not depend on blkid (-d), - outputs the scan results to kernel log to show what's being detected, as the system logger is not yet running.
