nspawn: bring back the word `may` in error text

In the change set 6c045a999800c62368470938307951bb669f5afc the error
text for the old flag `--private-users-chown` was repurposed for the
new flag `--private-users-ownership=own` and while doing so the word
`may` was dropped leading to a grammatically incorrect error text.
