entry_cnp: disable the primary selection type from entry

entry_cnp: disable the primary selection type from entry

Since the wayland protocol does not support multiple
selection types, many issues related to the multiple
selection types happens.
We disable the primary selection type to fix related
bugs of clipboard copy paste.
When the wayland protocol supports multiple selection
types, we should enable all types in entry.
TC: copy text to entry, add new text, select all text,
paste -> selection remained, text is not pasted.
