udevadm-wait: let --removed override initialization

The documentation says --initialized= is ignored when --removed is
specified.

Track --removed separately so it wins regardless of option order.

Reproducer:
  udevadm wait --timeout=0 --removed --initialized=no /dev/no-such-test-device

Before:
  Timed out for waiting devices being added.
