[lldb/cmake] Temporarily revive LLDB_DISABLE_CURSES

At least one lldb bot still uses this cmake variable instead of
LLDB_ENABLE_CURSES. Add code to set the default value of the "enable"
variable based on the old value of the "disable" setting.

This should bring those bots back up, until we can update the master to
use the new setting.
