LOG: [test][DebugInfo] Fix location of test build artifacts (#165349)

The test added in #161067 writes artifacts to the current dir, i.e.
`test.o` / `test.dwo` / `test.dwp`, which might not be writeable. Tests
should use `%t` for test artifact location, i.e. `%t.o` / `%t.dwo` /
`%t.dwp` However, since `"test.dwo"` is part of the assembly source file
used as a test input, and that's not something lit will substitute, that
typical approach doesn't work. We can instead ensure the output is in a
good location by running `cd %t` (after setting it up).
