Fix build of QTuioTouchPlugin with Makefile generator on macOS

Browse Source 
For each plugin, we create a custom target with it's OUTPUT_NAME such
that one simply can do 'ninja qtuiotouchplugin' to build it.

QTuiTouchPlugin has qtuiotouchplugin as OUTPUT_NAME, which is
problematic with Makefile generators on case-insensitive file systems.
See CMake upstream issue #21915 for details.

Work around this issue by not creating the custom target in this
situation.

Pick-to: 6.1
Fixes: QTBUG-84342
