pkg/report: allow to specify suppressions per OS

Currently all (linux-specific) suppressions are hardcoded in mgrconfig.
This is very wrong. Move them to pkg/report and allow to specify per OS.
Add gvisor-specific suppressions.
This required a bit of refactoring. Introduce mgrconfig.KernelObj finally.
Make report.NewReporter and vm.Create accept mgrconfig directly
instead of passing it as multiple scattered args.
Remove tools/syz-parse and it always did the same as tools/syz-symbolize.
Simplify global vars in syz-manager/cover.go.
Create reporter eagerly in manager. Use sort.Slice more.
Overall -90 lines removed.
