cmake: Copy correct file for Qt imageformat plugin

During CMake configuration for 64-bit builds, CopyMSVCBins.cmake would
copy plugins/imageformats/qsvg.dll from the Qt directory to
additional_install_files/exec64r/imageformats/qsvg.dll (exec32r for
32-bit builds). However, it would copy plugins/iconengines/qsvgicond.dll
to the corresponding debug imageformats files location,
additional_install_files/exec64d/imageformats/qsvgicond.dll (or exec32d
for 32-bit). This appears to have been a simple copy-paste mistake.
Let's copy plugins/imageformats/qsvgd.dll instead.
