In Qt 5.10 QGeoMapType need QGeoCameraCapabilities as argument
E.g: https://github.com/qt/qtlocation/blob/2b230b0a10d898979e9d5193f4da2e408b397fe3/src/plugins/geoservices/osm/qgeotiledmappingmanagerengineosm.cpp#L167
Fix #5916

This ensures no ports are being displayed to the user that are definitely unusable.

The earlier sleep calls disabled the app event queue, leading to "beachballing" in Mac OS and a visible boot delay / jitter. Running the event loop actively while waiting prevents the UI from freezing.

We were connecting to system peripherals before, which adds boot delay as QGC re-tries opening the port. We were also opening serial ports two times on Mac OS: Once as /dev/cu.usbmodem1 and once as /dev/tty.usbmodem1 - since the cu.usbmodem alias was already open, the 2nd opening always failed, leading to further boot delay.
