Remove old apache_hooks occurrence

The apache_hooks SAPI has been removed since PHP >= 7.0 and there is no
need to have two different php_request_startup definitions.

Also php_request_startup_for_hook() and php_request_shutdown_for_hook() functions
are not used in the PHP source code directly anymore. They are out of sync and
are not touched when making changes to the shutdown sequence.

The php_start_sapi() function was therefore not used anymore and is
removed.
