rust: pin-init: examples, tests: use `ignore` instead of conditionally compiling...

Change `#[cfg(cond)]` to `#[cfg_attr(not(cond), ignore)]` on tests.

Ignoring tests instead of disabling them still makes them appear in the
test list, but with `ignored`. It also still compiles the code in those
cases.

Some tests still need to be ignore, because they use types that are not
present when the condition is false. For example the condition is
`feature = std` and then it uses `std::thread::Thread`.
