tests/drv_hangman: remove check for other drm clients

From: Tim Gore <[email protected]>

This test will not run on Android as the coreu service remains running even after the android system is stopped. Coreu is a client of drm and when the test finds this it fails an assert.
Coreu is started by the init process and there is no tidy, non invasive way to stop it (init just restarts it). Coreu isn't doing anything and would not be expected to interfere with this test. In addition, all the other igt tests just rely on the user/test script to ensure that there are no other drm clients, so this test can do the same. On Android we must rely on coreu being dormant when this test runs.
