Make sure impersonation tests use a temporary AIRFLOW_HOME

[Taragolis]

Continuation of #30313

The impersonation tests of ours modify permissions for the AIRFLOW_HOME recursively. This is quite a bad idea when the tests are executed inside breeze with mapped folders (logs) because the logs folder ends up with being not readable by the owner.

Changing AIRFLOW_HOME in the fixture performig permission change should help with that.

Its great to see you again @Taragolis !

Well, sqlite test failure it is a bit expected, because impersonate user doesn't have access to /root/airflow/sqlite/airflow.db 🤔

Should not it be using the database in the temp AIRFLOW_HOME Then? We could simply add write access to that sqlite instanace and simply initialise and use it before every impersonation test as part of the "create_airflow_home" fixture. that sounds like best approach ?

As @Taragolis noted - the sqlite tests need a bit tweaking :)

Unfortunetly we initialise SQLite DB in {AIRFLOW_HOME}/sqlite/airflow.db, I've tried re-initialise it in test runtime in another place but without success (yet??).

The easiest solution in case of sqlite backend in breeze it would create DB in directory with 777 permissions and outside of AIRFLOW_HOME so everyone in breeze have access to this sqlite on read and write, I guess it is the same requirement for someone who want to use impersonation + sqlite

Feel free to merge as-is if you are ok with it too and do not want to make any more changes.
