If we explicitly set the user.home property, then Java doesn't consult
/etc/passwd to determine $HOME, fixing the problems that necessitated
updating /etc/passwd in the first place.

Because we use the Java user.home property to get the default
configuration directory, there needs to be an entry for the correct user
in /etc/passwd. For this to work with arbitrary UID/GID, that means
updating /etc/shadow dynamically based on the UID/GID in the container
before starting the application.
