test-libevdev-events.c: In function ‘test_double_syn_dropped_event’:
test-libevdev-events.c:187:2: warning: ignoring return value of ‘read’,
declared with attribute warn_unused_result [-Wunused-result]

This read was there to drain events even when there shouldn't be any on the
pipe anyway. So let's add an assert.
