Remove vivaldi from cnchi's selectable apps?

[manuel-192]

Problem:

Vivaldi is now removed from Antergos packages, but it still appears in the cnchi installer as an selectable package for installing. Selecting it makes the installer to fail.

Steps To Reproduce:

1. Start Antergos installer
2. Select vivaldi to be installed.
3. Install fails.

Additional Notes:

Seems that vivaldi should be removed from the cnchi's selectable packages list.
