Committing a symlink to aprun-utils.c and removing the copy in the Makefile

[reviewed by Thomas]

This commit checks in a symlink of the file aprun-utils.c in the
pbs-aprun directory.  It also removes the copying of that file as well
as fixes a type-o.

The copying of aprun-utils.c into the pbs-aprun directory was
problematic for the dependence checking, but I didn't notice b/c I
already had a rule for building aprun-utils.c in my repository at the
time.

Apparently SVN symlinks do not work on Window systems, but there are
no Windows systems than support aprun, so I'm not going to worry about
it.
