misc: Replace sha1() by hash('sha1', ...)

The dedicated `sha1()` function is proposed for deprecation with PHP 8.4:
https://wiki.php.net/rfc/deprecations_php_8_4#deprecate_md5_sha1_md5_file_and_sha1_file

For a future change it might also be considered to move to a cheaper hash
function. The xxHash family (available as `xxh*`) is faster and should be
sufficiently collision resistant for use within the cache.
