Add proc-macro boilerplate to crt-static test

I was seeing this failure when running ui tests with with a `-Cpanic=abort` stdlib targeting fuchsia:

```
---- [ui] tests/ui/proc-macro/crt-static.rs stdout ----
normalized stderr:
warning: building proc macro crate with `panic=abort` may crash the compiler should the proc-macro panic

warning: 1 warning emitted

The actual stderr differed from the expected stderr.
```

`force-host` was enough to stop it from running/failing, not sure if I should also add `needs-unwind`?
