scripts/qom-fuse: move to python/qemu/qmp/qom_fuse.py

Move qom-fuse over to the python package now that it passes the
linter. Update the import paradigms so that it continues to pass in the
context of the Python package.

-QEMU Object Model FUSE filesystem tool
-
-This script offers a simple FUSE filesystem within which the QOM tree
-may be browsed, queried and edited using traditional shell tooling.
-
-This script requires the 'fusepy' python package.
-
-
-usage: qom-fuse [-h] [--socket SOCKET] <mount>
-
-Mount a QOM tree as a FUSE filesystem
-
-positional arguments:
-  <mount>               Mount point
-
-optional arguments:
-  -h, --help            show this help message and exit
-  --socket SOCKET, -s SOCKET
-                        QMP socket path or address (addr:port). May also be
-                        set via QMP_SOCKET environment variable.
