Add chameleon video tests for Peppy.

Peppy joins jerry and pi in the list of devices that are running
video glitch tests with chameleon.

Once we onboard all devices, we will delete the individual control
files and just use one control file.

BUG=chromium:418217
TEST=Local test_that on a peppy device.
