Bug 300714 – [Win] Access is denied when removing files in WebKitBuild

• Component: Tools / Tests
• Status: RESOLVED FIXED

[Ian Grunert]

Sometimes there's files left in WebKitBuild that PowerShell and msys python is unable to remove, but the rm utility in bash is able to.

Make extractBuiltProduct use rm first to hopefully avoid this error.

```
python3 Tools/CISupport/built-product-archive --platform=win --release extract
 in dir C:\BW\Win-Tests-EWS\build (timeout 1200 secs)
 watching logfiles {}
 argv: [b'python3', b'Tools/CISupport/built-product-archive', b'--platform=win', b'--release', b'extract']
