Fix exporting SARIF files from scan-build on Windows.

In Perl, -z is defined as checking if a "file has zero size" and makes no mention what it does when given a directory. It looks like the behavior differs across platforms, which is why on Windows the SARIF file was always being deleted.

Patch by Joe Ranieri.
