[lld] Add `REQUIRES: riscv` to test added in 151639 to skip the test when riscv is not built. (PR #152858)

[via llvm-commits]

https://github.com/dyung created https://github.com/llvm/llvm-project/pull/152858

A test was added in #151639 which fails if the RISCV backend is not built, so add a `REQUIRES: riscv` to skip it when the backend is not present.
