[Buildroot] [PATCH] dialog: Override ncurses config script

[Maarten ter Huurne]

Without the override, systemwide ncurses6-config can be found instead
of ncurses5-config from staging.

My previous patch contained a bug: DIALOG_CONF_OPT was overridden
instead of appended to. This was not fatal on the build I tested it
with but can break other builds. Below is the corrected patch.
