[analyzer] PR41239: Fix a crash on invalid source location in NoStoreFuncVisitor.
It turns out that SourceManager::isInSystemHeader() crashes when an invalid
source location is passed into it. Invalid source locations are relatively
common: not only they come from body farms, but also, say, any function in C
that didn't come with a forward declaration would have an implicit
forward declaration with invalid source locations.
There's a more comfy API for us to use in the Static Analyzer:
CallEvent::isInSystemHeader(), so just use that.
