Previous commit 67aea3b fixed the test for paths with '/', expand it to include 
'\' to fix the same problem on Windows.

Our internal Windows builder hit the same issue that was previously fixed on 
linux, but on Windows since the temporary path that had generated contained 
'crt':

```
"ld" "--eh-frame-hdr" "--hash-style=gnu" "--enable-new-dtags" "-o" "a.out" "-r" 
"-LC:\\j\\w\\779ddbee\\build\\bin/../lib" "-L/usr/lib" "-L/usr/lib/gcc80" 
"c:\\j\\w\\779ddbee\\temp\\lit-tmp-8crtk3__\\dragonfly-1efec1.o" "-r"
```

This change adds the Windows patch separator '\' to the list of disallowed 
characters to prevent the problem on Windows.
