tools/syz-query-subsystems: introduce the kvm-x86 subsystem

Split off kvm-x86 from kvm for better coverage accounting.
Both subsystems will still share the CC lists, so bugs in x86 code
won't be emailed twice.

While at this, also fix the tool name in the generated comment and
regenerate pkg/subsystem/lists/linux.go on v6.14-rc7.
