config/linux-x230-maximized: add lvm thin provisioning and lvm snapshot support

modules/busybox: version bump to have better ash<-> bash compatibility
config/busybox.config: add truncate and other needed stuff
initd/etc/lvm/lvm.config: deactivate thin-provisioning binaries lookup
modules/blake2: bsum2 checksuming support (wyng-backups requirement, not under busybox)
modules/zstd: zstd 1.4.9 support (best compression algo, thanks to facebook. wyng-backup-extract.sh requirement)
 - pass ZSTD_LIB_MINIFY=1 to build to have -Os and other space optimized build
Makefile: add glue to pack blake2 and zstd if configured in board
boards/x230-hotp-maximized: add blake2 and zstd modules (working)

PR for wyng-extract (non-working.... still in the process of removing bashisms but was not completely successful):
tasket/wyng-backup#104

missing: softlink to have zstdcat (have to create it manually under Heads as of now, tried to replicated busybox do call for symlink, but the target is just skipped.
