GNUInstallDirs: avoid unwanted variable dereference

Browse Source 
In some situations, it seems that the variable `0` is defined. In the
case found, it was set to `1`. This makes the detection of the missing
third argument bogus and unnecessarily triggers a warning.

This oversight was introduced in 229b5ee994 (GNUInstallDirs: Add dir
argument to GNUInstallDirs_get_absolute_install_dir, 2020-10-31) prior
to CMake 3.20's release cycle.
