ci: Enable the wasm-wasi-component tests

We now have tests for this module via commit cad6aed ("Tests: initial
"wasm-wasi-component" test").

We need to install cargo-component for this test target.

Also the only way I found I could get this test to run was by running as
non-root. The issue I was seeing was that despite cargo being installed
into /home/runner/.cargo/bin *and* that being in the path, it kept
claiming it couldn't find cargo. E.g.

  $ sudo -E echo $PATH

Showed /home/runner/.cargo/bin in there.

  $ sudo -E /home/runner/.cargo/bin/cargo -V

Worked.

  $ sudo -E cargo -V

cargo command not found.

(Also other oddities, despite claiming to be using bash, it couldn't
find shell builtins like 'hash' and 'export', perhaps some Ubuntu
weirdness...)

However, no problem, there is *no* need for it run as root anyway so
result!
