tests: Normalize \r\n to \n in some run-make tests

The output is produced by printf from C code in these cases, and printf prints in text mode, which means `\n` will be printed as `\r\n` on Windows.
In --bless mode the new output with `\r\n` will replace expected output in `tests/run-make/raw-dylib-*\output.txt` files, which use \n, always resulting in dirty files in the repo.
