[toolchain-utils] Fix remaining lint errors in toolchain-utils.

In addition to fixing the lint errors, this also fixes the Python
formatting issues (ran tc_pyformat on nearly all the files).

BUG=chromium:570450
TEST=Ran all crosperf & bisect tool unit tests.
     Ran afe_lock_machine.py (check machine status)
     Ran full crosperf test (octane, speedometer, BootPerf) on alex.
