btest/input/raw: Fix reread test

Browse source 
This seems to have relied on the reading file twice behavior simply
testing that 16 lines are observed. Switch to using two separate
files and doing a system("mv ...") to trigger the REREAD logic, there's
not force_update() needed and it wouldn't do anything if the file
hadn't changed anyway.
