Convert RISC-V numeric identifiers to strings

Printing the register values as part of the stack trace relies on the
CPU architecture being "riscv" or "riscv64" rather than the numeric
identifiers (0x8005 and 0x8006, respectively).

Fixed: 1432306

Test: Run `minidump_stackwalk` on a RISC-V minidump
