osage: CMake define NEATOGEN_EXPORTS

osage is part of the neato_layout plugin.

Fixes errors like this using CMake with MinGW:

C:/tools/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/10.3.0/../../../../x86_64-w64-mingw32/bin/ld.exe: lib/osage/libosage.a(osageinit.c.obj):osageinit.c:(.text+0x2ec): undefined reference to `__imp_neato_init_node'
