Kenjiro Nakayama 8c8d236f42 xtask: codegen: generate bindings for user_regs_struct
This patch adds `user_regs_struct`.

riscv provides struct user_regs_struct instead of struct pt_regs to userspace.
After bindings generates the code, adding the riscv support in `bpf/aya-bpf/src/args.rs`
then aya-bpf can be built for riscv.
