[libc-commits] [libc] Disable prctl test when building for arm or riscv. (PR #143627)

[Amy Huang via libc-commits]

https://github.com/amykhuang created https://github.com/llvm/llvm-project/pull/143627

I'm setting up a buildbot for arm32 using qemu and qemu doesn't support PR_GET_THP_DISABLE.
Disable the test for now while we figure out what to do about that.

Also disable for riscv because we may do the same for riscv buildbots.
