Add EM_RISCV as recognized value for ELF e_machine

`dump_syms` fails to write symbol file without knowing how to convert
the ELF `e_machine` field to a string.

Use "riscv" as the value because ELF `e_machine` does not distinguish
between 32 bit and 64 bit RISC-V.

Test: run `dump_syms` on the libc++ that's shipped with the Clang
toolchain, or any other riscv binary: `./dump_syms -r -n libc++.so -o
Fuchsia <clang_path>/lib/riscv64-unknown-fuchsia/libc++.so.2.0`
