Add details to bug template

A large number of bugs get filed against OpenBMC forks, and platforms
that are not upstream.  Change the wording on the bug template to make
clear the fields should be expected to be from upstream, and explicitly
call out if qemu builds are being used, to help in maintainers
reproducing.

Tested:
N/A, documentation change.
