fix(gh-151626): handle frozen os.path on Windows in test_aliased_target

On Windows, os.path resolves to ntpath which is a frozen module
(origin='frozen', cached=None). Calling cache_from_source('frozen')
fabricates a nonsensical path that mismatches the subprocess output of
None. Guard the cache_from_source call on cached being non-None.
