selftests: netfilter: nft_concat_range.sh: move to lib.sh infra 

Use busywait helper instead of unconditional sleep, reduces run time
from 6m to 2:30 on my system.

The busywait helper calls the function passed to it as argument; disable
the shellcheck test for unreachable code, it generates many (false)
warnings here.
