Update 250_find_all_libs.sh

Removed unreliably working code that intends to filter out
duplicates in the LIBS and COPS_AS_IS arrays via
echo "${ARRAY[@]}" | tr ' ' '\n' | sort -u | tr '\n' ' '
that fails when array elements contain spaces
so better code should be used e.g. like
printf '%s\n' "${ARRAY[@]}" | awk '!seen[$0]++'
but filtering out duplicates is not needed, see
#2377
and by the way cleaned up the whole script a bit.
