rust: macros: ignore example with module parameters

`ModuleParamAccess` uses `SetOnce`, which depends on the helper functions
so the `macros` crate example under `rusttest` fails to build:

    ---- rust/macros/lib.rs - module (line 62) stdout ----
    error: linking with `cc` failed: exit status: 1
      |
      = note:  "cc" "-m64" ...
      = note: some arguments are omitted. use `--verbose` to show all linker arguments
      = note: rust-lld: error: undefined symbol: rust_helper_atomic_try_cmpxchg_relaxed
              >>> referenced by kernel.ecd446ce39a5fcbb-cgu.3
              >>>               kernel.kernel.ecd446ce39a5fcbb-cgu.3.rcgu.o:(kernel::sync::set_once::SetOnce$LT$T$GT$::populate::h8b02644e30bd70bc) in archive ./rust/test/libkernel.rlib

              rust-lld: error: undefined symbol: rust_helper_atomic_set_release
              >>> referenced by kernel.ecd446ce39a5fcbb-cgu.3
              >>>               kernel.kernel.ecd446ce39a5fcbb-cgu.3.rcgu.o:(kernel::sync::set_once::SetOnce$LT$T$GT$::populate::h8b02644e30bd70bc) in archive ./rust/test/libkernel.rlib
              collect2: error: ld returned 1 exit status

Thus ignore that example to fix the error.

[ Only the first one is needed (the other example does not use
  parameters), so we can keep it enabled. Thus I removed that second
  deletion (and reworded a bit).

  We may want to do something better here later on; on the other hand,
  we should get KUnit tests for `macros` too eventually, so we may end
  up removing or repurposing that target anyway, so it is not a big deal.
