Revert "Keep the native terminal active when enabling gfxterm"

This can cause an issue where GRUB is trying to display both a text and
graphical menu on the display at the same time, resulting in a flickering
effect when e.g. scrolling quickly through a menu (LP: #1752767).

Revert for now while we look for a better solution for the original issue.

This reverts commit 52ef7b23f528ce844716661d586497a177e80d5b.
