gdbus: Add missing GUnixFDList variable declaration

Could you add a test-case which triggers this problem?

Just for completeness, the test-suite failures with this patch:

tests/_test/main.c: In function ‘dbus_enum_string_marshalling_test_proxy_test3’:
tests/_test/main.c:85010:15: error: redeclaration of ‘_fd_list’ with no linkage
  GUnixFDList* _fd_list;
               ^~~~~~~~
tests/_test/main.c:85007:15: note: previous declaration of ‘_fd_list’ was here
  GUnixFDList *_fd_list;
               ^~~~~~~~
tests/_test/main.c: In function ‘dbus_filedescriptor_client_test_proxy_test_in’:
