We need the polyfill for `json_last_error_msg` which is part of php 5.5, not 5.4.

Security-core no longer directly depends upon polyfill-util since #16382.

This does not change the existing dependancy tree as polyfill-util is
transitivly depended on via polyfill-php56.

Applies #22709 to the two higher-level packages. I've applied it to 3.3 as that's where that change was merged (though it was `master` as the time); these may actually apply earlier though?

(#16382 was mentioned and applied to 2.8, though is for the serializer which is unrelated? Should have been 3.0 when `StringUtils` was removed?)
