Fix #77609: Tests from mailparse extension fails

Add installed php extensions to temporary created ini file

In php extensions configured with phpize, a temporarily generated
php.ini is used for testing, but currently contains no installed
PHP extensions, which is required by the mailparse extension,
for example.

Installed extensions must be added with their absolute path,
because the extension_dir parameter is already occupied.
