Android: Update script with sync progress

When running lots of traces, there can be a long pause
when syncing traces to the device.

Add a small update so it is clear that work is happening.

Example output:

I12:21:51.806619Z Syncing 1945_air_force trace (1/238)
I12:21:52.178401Z Syncing 20_minutes_till_dawn trace (2/238)
I12:21:52.463608Z Syncing 2_3_4_player_mini_games trace (3/238)
...

Test: angle_trace_tests
Bug: b/276742336
