nspawn: allow to bind mount journal on top of a non empty container journal dentry

Currently if nspawn was called with --link-journal=host or
--link-journal=auto and the right /var/log/journal/machine-id/ exists
then the bind mount the subdirectory into the container might fail due
to the ~/mycontainer/var/log/journal/machine-id/ of the container not
being empty.

There is no reason to check if the container journal subdir is empty
since there will be a bind mount on top of it. The user asked for a bind
mount so give it.

Note: a next call with --link-journal=guest may fail due to the
/var/log/journal/machine-id/ on the host not being empty.
