[clang] clang: Fix broken --offload-arch arguments in tests (PR #195259)

[Matt Arsenault via cfe-commits]

https://github.com/arsenm created https://github.com/llvm/llvm-project/pull/195259

These need to use 2 dashes. A single dash is interpreted as -o. Fix
this in all tests using the single dash, except one which appears
to be testing the behavior of warning on the misspelled argument.
