feat(php-rpc): implement phpinfo() capture over RPC

DiagnoseCommand::check_platform needed phpinfo() output but
shirabe-php-shim's ob_start()/phpinfo()/ob_get_clean() are unmodeled
todo!()s. Add a phpinfo dispatch entry to the PHP worker (capturing
output the same way extension_info already does) and a get_phpinfo()
wrapper, then switch check_platform to call it directly.

This unblocks the phpinfo-related panic in diagnose; the ignored
tests now hit a separate RefCell double-borrow bug in check_http, so
their ignore reasons are updated to point at that instead.
