selftests/bpf: Enable stack argument tests for RV64
Enable the stack argument selftests for RV64. The riscv guard is
restricted to __riscv_xlen == 64 since stack arguments are only
supported by the RV64 JIT.
Keep the __BPF_FEATURE_STACK_ARGUMENT gate, defined by clang with
BPF stack argument support [1].
