incr-check: deal with Windows stupidity

Browse Source 
The real problem here is that Git for Windows has horrendous defaults
which convert LF to CRLF. However, rather than changing this
configuration on the CI runners, it's worth supporting inexplicable CRLF
in these files so that anyone else cloning Zig on Windows doesn't get
unexpected test failures.
