[OE-core] [RFC][PATCH 6/6] local.conf.sample: make debug-tweaks depend on IMAGE_MODE

[Patrick Ohly]

Enabling "debug-tweaks" unconditionally, even if it is only in the
local.conf.sample file, runs the risk of that getting used in
production images.

By checking the per-image IMAGE_MODE, the debug tweaks only get
enabled for images not meant for production.
