Run sysdiagnose at the end of Azure Pipelines jobs on macOS

This runs this with quite a lot of arguments, mostly to exclude the
generated and/or time-sensitive logs, along with the larger log
archive, for the sake of making this a sensible amount to store for
each run.

Notably, this does include crash and spin logs, which have already
proven useful to track down intermittent crashes on Azure Pipelines.
