Fix building of callgraph including preloaded symbols

This issue was introduced in phpGH-15021. When building the call graph, we can now
see preloaded functions. However, building the call graph involves mutating the
callee, which we don't want to do for functions not coming from the script,
especially because the call graph is released later on.

Fixes phpGH-15490
