[libc] Use a sensible default when TEST_UNDECLARED_OUTPUTS_DIR is unset. (#167422)
There is no guarantee that this environment variable is set. Eg, when
running a test outside of the build system, such as under a debugger.
And passing a nullptr to the string constructor is undefined.

Use an empty string, which seems like it is close to the original
intent.
