eCTS: Run openocd and lsusb as a root
Running lsusb (to get iSerial) and openocd requires a privilege.
This patch makes cts.py run these commands as a root. Opening
ttyACM0 requires a privilege as well but it'll be done by asking
a user to add themselves to dialout group.
BUG=chromium:664309
BRANCH=none
TEST=Run cts.py on a freshly set up cros_sdk chroot.
