aoc_u: Make use of previously-unused CheckAOCTitleIDMatchesBase() function

We can just call the function instead of duplicating the code here. This
also prevents an unused function warning.

We also don't need to take the lambda capture by reference. It's just a
u64 value, so by value is fine here.
