jail: set default root directory for a jail to its parent's root.HEADmain

All default jail parameter values are an empty or otherwise standard
value, or are copied the jail's parent.  A notable exception is the
root directory, which is instead copied from the creating process's
jail.  Fix that to be in line with everything else.

This change affects only the default when no path is specified; if
a path of "/" is explicitly given, that will still be the creating
process's root directory.
