switch to 4 space indent

Leave the recipes/ code at 2 space to match the rest of the recipes
project in other repos.

Reformatted using:
files=( $(
	git ls-tree -r --name-only HEAD | \
		grep -Ev -e '^(third_party|recipes)/' | \
		grep '\.py$';
	git grep -l '#!/usr/bin/env.*python' | grep -v '\.py$'
) )
parallel ./yapf -i -- "${files[@]}"
~/chromiumos/chromite/contrib/reflow_overlong_comments "${files[@]}"

The files that still had strings that were too long were manually
reformatted because they were easy and only a few issues.
autoninja.py
clang_format.py
download_from_google_storage.py
fix_encoding.py
gclient_utils.py
git_cache.py
git_common.py
git_map_branches.py
git_reparent_branch.py
gn.py
my_activity.py
owners_finder.py
presubmit_canned_checks.py

reclientreport.py
roll_dep.py
rustfmt.py
siso.py
split_cl.py
subcommand.py
subprocess2.py
swift_format.py
upload_to_google_storage.py

These files still had lines (strings) that were too long, so the pylint
warnings were suppressed with a TODO.
