URL: https://github.com/apache/airflow/issues/19206
### Apache Airflow version
2.2.0 (latest released)
### Operating System
Red Hat Enterprise Linux Server 7.6 (Maipo)
### Versions of Apache Airflow Providers
_No response_
### Deployment
Virtualenv installation
### Deployment details
For this usecase - I am testing with a non-root user on a machine where the
user does not have write access to /tmp.
The `TMPDIR` environment variable is set to a different directory.
### What happened
When running webserver, errors like this are shown and slow down the
webserver.
```
[2021-10-25 13:46:51,164] {filesystemcache.py:224} ERROR - set key
'\x1b[01m__wz_cache_count\x1b[22m' -> [Errno 1] Operation not permitted:
'/tmp/tmpbw3h3p93.__wz_cache' -> '/tmp/2029240f6d1128be89ddc32729463129'
```
### What you expected to happen
Airflow should respect the `TMPDIR` environment variable and use a different
temp dir
### How to reproduce
