wm: Better wayland detection

fix in mac can not make_thumbnail

add Sabotage linux package support

ascii: add LEDE

distro: fix trueos detection

disk: change Haiku's df detection

# fix in mac high Sierra cannot replace '/' with '_', optionally can use ${image//\//_}

'blocks' keyword is also present in busybox' df.
Busybox' df also has -P and -h flags, so it can be detected as normal df.
'Tracker' keyword seems to be exclusive to Haiku's df.
