grub: disable floating ncurses dependency for GPLv2 version
A dependency was being added on ncurses conditionally upon whether it
had been built first. Explicitly disable this dependency to stop this
from happening.
Note that grub 2.x does not need this same fix because there ncurses is only
used when building grub-emu, which is only built when the specified
target platform is "emu" which we do not use.
