refactor(tests): share the PHP worker helpers with the plugin binary

plugin_installer_test.rs carried its own copy of php_runtime_available,
lock_php_worker and load_composer_php_runtime, and the other ten files
in the binary imported them from there. The bodies matched
tests/common/php_worker.rs, so include that instead.
