executor, sys/linux, pkg: enable syzos for riscv64
This patch enables syzos for riscv64 and implements
the corresponding pseudo syscalls.
Pseudo syscalls:
- syz_kvm_setup_syzos_vm
- syz_kvm_add_vcpu
- syz_kvm_assert_syzos_uexit
Syzos guest support:
- guest_uexit
- guest_execute_code
- guest_handle_csrr and guest_handle_csrw
Test seeds:
- riscv64-syz_kvm_setup_syzos_vm
- riscv64-syz_kvm_setup_syzos_vm-csrr
- riscv64-syz_kvm_setup_syzos_vm-csrw
