Include of autogenerating files are not idempotent

[websi]

The path to file typo3/alias-loader-include.php is an absolute path.
Composer use an hash to the file for the include.
So the hash changes for different paths. This is very common in the CI system.
This prevents effective caching of the generated files.

Similar use cases from composer: composer/composer#7049 and composer/composer#11226
