Remove SMACK rule file(.rule) according three domain model

Remove SMACK rule file(.rule) according three domain model

Since SMACK only allows three labels, "_"(floor), "User", "System"
The labels of current rule file are not appropriate

Solution:
- Remove rule file (org.tizen.menu-screen.rule)
- Remove install statement about installing rule file described in CMakeLists.txt
- Remove file path and name declaration of spec file (packaging/org.tizen.menu-screen.spec)
