selftests/bpf: libarena: Directly return arena pointers from functions

Browse source

Now that the __arena annotation includes a BTF type tag, and the
verifier can identify arena pointers at BTF loading time, return
arena pointers as their true type instead of casting to u64. Remove the
preprocessor typecast wrappers used to hide this from the caller.
