test: rename usb_prl to usb_prl_old

In preparation for moving the usb_prl unit test from the simulation
to mocks, rename the current test to _old. We will set up a new
usb_prl test that uses mocks and move the tests over in a controlled
fashion.

BUG=b:158608129
BRANCH=None
TEST=`TEST_LIST_HOST=usb_prl make runhosttests` works.
