You never nest {{...}} markers. You're already inside a Jinja context, so you can just write variables normally:

- name: var to trim  
  set_fact:  
    trim_var: "{{ groupname.split('test-' ~ env ~ '-') }}"

Note that the Jinja ~ operator behaves like +, but it will convert its operands to strings first (which doesn't matter in this case, but is quite useful if you're dealing with variables that are not strings).
