check-available-binaries: Use 'substitutable-paths'.

Browse Source 
* build-aux/check-available-binaries.scm: Rewrite to use 'substitutable-paths'
  instead of 'substitution-oracle'.  The latter does more than we need, and it
  no longer check the substitutability of valid items, which is not what we
  want.  Use 'lset-difference' instead of iterating over the items.
