hdctools: servo: Properly import HwDriverError

When catching exception from drivers, we want to be able to catch
HwDriverError. However, since HwDriverError is not properly imported to
current namespace, we actually generate an AttributeError when trying to
catch the original exception. This CL imports HwDriverError so that this
doesn't happen.

BUG=chrome-os-partner:10908
TEST=Generate an 'ecError' in EC driver and see the correct error
message using dut-control.
