[LLVM-C] Use NameLen in LLVMGetNamedGlobalAlias

[Wallbraker]

Summary

I tried to look over the file and didn't see any other non-use of *Len variables.

Thanks.

Thank you for the quick review, I don't have commit access so I will need help to have it land.

I have no idea what the build test error is about, looks super unrelated.
