rG9816e726e747: [Driver][RISCV] Add RedHat Linux RISC-V triple
Summary

Adds the RedHat Linux triple to the list of 64-bit RISC-V triples. Without this the gcc libraries wouldn't be found by clang on a redhat/fedora system, as the search list included /usr/lib/gcc/riscv64-redhat-linux-gnu but the correct path didn't include the -gnu suffix.
