cmake: Fix some Qt DLLs not being copied due to filename patterns

Qt has some Release DLLs that end with the letter d:
* qdirect2d.dll
* qcertonlybackend.dll
* qopensslbackend.dll
* qschannelbackend.dll

As a result, they get caught by our simple check for if a DLL is a Debug
DLL which just checks if the DLL ends with the letter d.

Extend that check to exclude these specific DLLs from being marked as
Debug DLLs.
