[Driver][test] Add libclang_rt.profile{{.*}}.a tests for OpenBSD

[fcambus]

Summary

This was requested in D109244.

It needs D109051 to be applied for the OpenBSD driver to generate the correct library names, otherwise we always get libcompiler_rt.a.

clang/test/Driver/coverage-ld.c

Don't add //\n by cargo cult. It's not a recommended style (Having blank lines helps { } in Vim like editors)

Note: the new recommended libclang_rt* hierarchy is LLVM_ENABLE_PER_TARGET_RUNTIME_DIR=on. This matches LLVM_ENABLE_RUNTIMES='compiler-rt;libcxx;libcxxabi;libunwind'.

OpenBSD hasn't switched, though.

With the new hierarchy, the location may look like: lib/x86_64-unknown-openbsd/libclang_rt.profile.a
