* clif-util: Make the `-t` flag work with the `wasm` subcommand

The presence of the flag was checked in the code, so it was essentially already
supported, but it was not properly configured when constructing
the CLI arguments parser.

* clif-util: also enable the `-c` flag for the `wasm` subcommand

Similar to the parent commit, this functionality is already supported, just a
mix up of the CLI parser construction made it not show up.
