tests: Change how we wait for an orientation change

Browse source 
Previously, we were waiting up to 300ms for the signal, then proceeding
anyway. However, 300ms is not necessarily long enough to wait on an
autobuilder that might be heavily loaded, particularly if it's a non-x86
with different performance characteristics.

Conversely, if mutter responds to the D-Bus signal from the mock sensor
before we have connected to the signal, then we cannot expect to receive
the signal - it was already emitted, but we missed it. In this case, we
need to avoid waiting.

One remaining use of wait_for_orientation_changes() that would previously
always have timed out was in
meta_test_orientation_manager_has_accelerometer(), which does not
actually expect to see an orientation-changed signal. Make this wait
for the accelerometer to be detected instead.
