[clang-tidy] Fix fragile test in read-parameters-from-file (#171033)

[CommandLine.cpp](https://github.com/llvm/llvm-project/blob/fb0400fe1f1f9e83f3148db8ce2c72ab5bc6728e/llvm/lib/Support/CommandLine.cpp#L940)
treats single quote as literal characters on Windows, so the argument is
parsed as a check named `' -*,llvm-namespace-comment '`, which matches
no existing checks, so no checks are enabled via the command line.

Previously, the test passed because it fell back to the root
`.clang-tidy` configuration which enables `llvm-*`.
