Keep _sysconfigdata.py in image

The previous logic for keeping this file in the image did
not work well when building an SDK (the packaging layout
is different). This change works in all cases and is more
efficient.

Tested: Verified normal image and SDK build fine now
for witherspoon.

Resolves openbmc/openbmc#3384
