cts: Add real interrupt test
Interrupt test checks whether DUT can be interrupted by an interrupt
and an interrupt handler can be invoked as expected.
Note the previous interrupt test ported from test/interrupt.c runs in
an emulated environment on the host, thus does not test the real
interrupt capability of the chip.
BUG=chromium:653195
BRANCH=none
TEST=Run cts.py -m interrupt
