Spandan Das 559132fb98 Apply pylint to scripts/hiddenapi/verify_overlaps*
1. Run pyformat scripts/hiddenapi/verify_overlaps.py -s 4
--force_quote_type none -i to fix formatting. Some double quotes change
to single quotes since pyformat enforces consistent quotes
2. Wrap #pylint: (enable|disable)=line-too-long in tests

Test: m verify_overlaps verify_overlaps_test
Test: pylint --rcfile tools/repohooks/tools/pylintrc <file1>
<file1_test>
Bug: 195738175
