ui/gtk: Fix GTK assertion failure introduced with clipboard fixes

Browse Source 
gtk_clipboard_request_targets actually returns n_targets == -1
when targets ==  NULL instead of zero. This result in failed assertion
within GTK:

qemu: Gtk: gtk_targets_include_text:
assertion 'targets != NULL || n_targets == 0' failed

Extend the check to require non-null targets and positive n_targets.
