target/riscv: Fix privilege mode of G-stage translation for debugging

G-stage translation should be considered to be user-level access in
riscv_cpu_get_phys_page_debug(), as already done in riscv_cpu_tlb_fill().

This fixes a bug that prevents gdb from reading memory while the VM is
running in VS-mode.
