fetch_configs: switch to 4 space indent

Reformat this dir by itself to help merging with conflicts with other CLs.

Reformatted using:
parallel ./yapf -i -- fetch_configs/*
~/chromiumos/chromite/contrib/reflow_overlong_comments fetch_configs/*

The 2 files that still had strings that were too long were manually
reformatted.
