pycurl 7.45.3 compatiblity fix

[ap-wtioit]

When using pycurl the newest 7.45.3 is not compatible with python:3.8-slim-bullseye and python:3.10-slim-bookworm, see pycurl/pycurl#834

As a fast fix we added 210-fix_ca_bundle_pycurl.sh to our images build.d directory:

#!/usr/bin/env bash
# workaround for https://github.com/pycurl/pycurl/issues/834
if [[ -e /etc/ssl/certs/ca-certificates.crt && ! -e /etc/pki/tls/certs/ca-bundle.crt ]]; then
    echo "Symlinking /etc/pki/tls/certs/ca-bundle.crt for pycurl"
    mkdir -p /etc/pki/tls/certs/
    ln -s /etc/ssl/certs/ca-certificates.crt /etc/pki/tls/certs/ca-bundle.crt
fi

This prevents getting the following error (output from our own test):

Traceback (most recent call last):
  File "/opt/odoo/custom/bin/test_pycurl", line 10, in <module>
    curl.perform()
pycurl.error: (77, 'error setting certificate verify locations:\n  CAfile: /etc/pki/tls/certs/ca-bundle.crt\n  CApath: none')
