CMCMakeModules/UseCompat.cmake: fix list(REMOVE_ITEM ...)

When using a cmake version <= 3.19 the compat check fails with: CMake Error at CMakeModules/UseCompat.cmake:48 (list): list sub-command REMOVE_ITEM requires two or more arguments. To solve the issue we simply add an empty element "". Signed-off-by: Heiko Thiery <[email protected]>
