machined: add new OpenRootDirectory() call to Machine objects
This new call returns a file descriptor for the root directory of a container.
This file descriptor may then be used to access the rest of the container's
file system, via openat() and similar calls. Since the file descriptor returned
is for the file system namespace inside of the container it may be used to
access all files of the container exactly the way the container itself would
see them. This is particularly useful for containers run directly from
loopback media, for example via systemd-nspawn's --image= switch. It also
provides access to directories such as /run of a container that are normally
not accessible to the outside of a container.
This replaces PR #2870.
Fixes: #2870
