[RFC PATCH v2 118/137] sysbus: Parent main-system-bus directly under /machine

The main system bus is the only object deliberately placed under
/machine/unattached; every other resident is an accidental orphan.
Promoting it to /machine/sysbus makes /machine/unattached a pure
bug indicator that later commits can turn into a hard error.

The canonical path changes from /machine/unattached/sysbus to
/machine/sysbus.  qom-list users that hard-code the old path need
to be updated; the hmp/qmp qom-tree output naturally follows.
