Update test_lock_unlock_test_check() assertion to cope with new timings

With the DEEP_SLEEP_TEST_CHECK_WAIT_DELTA_US increased,
we now have TEST_ASSERT_UINT64_WITHIN(delta=1000, expected=1000, actual=1000)
so this assertion needed to be updated.

What we need is the deep sleep to be enabled after the programed interrupt
has fired and before a 2ms timeout expiration, which means >= 1000 and < 2000.
