eldritch horrors

this is used in CA rewriting, replacement of placeholders in derivations, generating scripts for devShells, and some more places. in all of these transitive replacements are unsound, and overlapping replacements would be as well. there even is a test that transitive replacements do not happen (in the CA RewriteSink suite), but none for overlapping replacements. a minimally surprising binary rewriter surely would not do any of these replacements, the only reason we have not seen this break yet is probably that rewriteStrings is only called for store paths and things that look like store paths (and those should never overlap nor admit such transitive replacements) Change-Id: I6fc29f939d5061d9f56c752624a823ece8437c07
