Add `miniconda_tmp_dir` var

This is very nice to have, because on some systems, /tmp is mounted with noexec and running the miniconda installer from it errors out with something like:

TASK [ansible-miniconda : installing....] *****************************************************************

The solution is to allow using a different TMPDIR as described at https://stackoverflow.com/questions/60106630/conda-exe-error-while-loading-shared-libraries-libz-so-1

Without this, I get errors like the above while trying to provision an Amazon Linux EC2 instance. With this, I can put this in my playbook:

     - name: Include ansible-miniconda role
       import_role:
         name: ansible-miniconda
       vars:
         miniconda_make_sys_default: True
         miniconda_tmp_dir: "{{ ansible_env.HOME }}/tmp"
       tags: miniconda

and it works.
