runat: Add -h to manipulate a symlink's named attribute dirHEADmain

Lionel Cons <lionelcons1972@gmail.com> requested
that a new option be added to runat(1) so that it could
be used to manipulate named attributes associated with
a symbolic link and not the file the symbolic link refers to).

This patch adds the option -h/--nofollow to do this.
