ci: Move --usecli --extended from i386 task to alpine task #35230

The i386 task is getting increasingly tedious to maintain:

• It is using deprecated (disabled by default) syscalls, see commit 999e9dbfb43e7e38f72e9b38fb3743022c2b9f80
• Running it on (e.g.) aarch64 is slow, due to the additional qemu overhead

It is mostly kept to have some more 32-bit coverage for #32375. But maybe in 5 or 10 years, it can be removed .... ?

So for now, try to reduce the config it runs by moving it out to longer-term tasks.

Specifically, move TEST_RUNNER_EXTRA="--v2transport --usecli --extended" to the native Alpine task, which should exist long-term, runs natively, and also has a debug build enabled.

Not a CI expert, but the change makes sense to me.
