man: symlinks are made onto "unit files", not "units"

We should be careful when talking about "units" and "unit files". The
latter should be the concept on disk, and the former, the loaded version
of it. However, as a single unit file can result in multiple loaded
units (think templates), and a units can also exist with no unit file at
all (think .device units), we should be precise.

As symlinks are created on unit files rather than units (as symlinks are
an fs object, and unit files are too, but units are not), let's say so
here.
