Fix not display the FDN menu if a SIM doesn't support FDN

The FDN menu is displayed even if a SIM doesn't support FDN function.
If user tries to enable it and add numbers in the FDN list in this case,
they fails. So, the FDN menu should be hidden.

Test: manual - Checked the FDN menu is not displayed if a SIM doesn't
support FDN
Test: auto - Passed CallFeaturesSettingTest
