Fix GH-10928: PHP Build Failed - Test curl_version() basic functionality [ext/curl/tests/curl_version_basic_001.phpt]

It's possible that curl was compiled without SSL, and/or without libz
support. In the case of the issue reporter it was without libz support.
This causes the test to fail because we expect a non-empty string.
Fix it by using %S instead of %s to allow empty strings.

Closes GH-10930.
