CI: Drop broken template building

We don't use the template and its `wry` feature in this fork.
Remove it now that `ubuntu-latest` no longer has the necessary
packages which requires a tedious and complicated upgrade
of the `wry` "nonsense".  This is attempted upstream at:
https://github.com/rust-mobile/xbuild/pull/210
