    meson: Fix build from tarball
    
    Since https://gitlab.gnome.org/GNOME/gimp/-/commit/2afa019c708869ef84a2d24c96552b380a504d4d,
    the Meson configure step will fail when building from tarball (missing `.git` and `gitversion.h` is 
present)
    because `gitversion_h` variable will contain a `list[file]` but `custom_target` does not like that in its 
`depends` kwarg.
