refactor: remove jq toolchain (#1186)

Follow-up promised in bazel-contrib/tar.bzl#37 
The toolchain is ported in
bazel-contrib/jq.bzl#31

Also remove assert_json_matches, this is now in jq.bzl:
bazel-contrib/jq.bzl#30

BREAKING CHANGE:
Anyone using the toolchain type themselves will have to get it from
jq.bzl instead. This would only be an obscure case if users compiled
their own jq from source, or wrote custom rules that take a jq toolchain
to resolve a jq binary.
