Fix typo BR2_TARGET_ROOTFS_SQUASHFS_BS_84K
-> BR2_TARGET_ROOTFS_SQUASHFS_BS_8K added by commit
555f8dfd6e and raising the following build
failure:

/nvmedata/autobuild/instance-0/output-1/host/bin/mksquashfs: -b invalid block size

Fixes:

Use options to increase compression ration as much as
possible, like using architecture-specific options, at
the cost of time when assembling the filesystem image.
For example:
- with gzip and lzo, use -Xcompression-level 9
- with xz use arch-specific bcj (branch-call-jump) filters
- with zstd use -Xcompression-level 22
- and more
