Consider symlinking fusermount3 to fusermount if the latter doesn't exist

[markstos]

Attempting to use restic mount failed out of the box on Fedora Linux today, because it provides fusermount3 and not fusermount.
After symlinking /usr/local/bin/fusermount3 to /usr/bin/fusermount, Restic could succeed.

I suggest this role check for the case where fusermount is missing but fusermount3 is present. In that case add a symlink, as above.

By adding the symlink in /usr/local and not /usr/bin, it should not interfere with actual package files.

Something like the following. I could create a PR for if there's agreement:

    - name: Check if fusermount is available
      tags: fuse
      ansible.builtin.command: which fusermount
      register: fusermount_check
      ignore_errors: true

    - name: Check if fusermount3 is available
      tags: fuse
      ansible.builtin.command: which fusermount3
      register: fusermount3_check
      ignore_errors: true

    - name: Create symlink for fusermount3 (if it exists and fusermount does not)
      tags: fuse
      # (Return code of zero is success)
      when: 
        - fusermount_check.rc > 0
        - fusermount3_check.rc == 0
      ansible.builtin.file:
        src: /usr/bin/fusermount3
        dest: /usr/local/bin/fusermount
        state: link
