scripts/dts: Remove dead 'aliases' check in insert_defs()

insert_defs() is the only function that adds keys to 'defs', and they
always get added with an 'aliases' key.

This function could get super simple if the duplicate-removal code could
be removed. It only seems to be needed to prevent duplicates for some
(unfortunately tricky) flash-related stuff now.
