We do this for consistency with the other -program-name variables for
programs within exec-directory.  Moreover, Lisp other than vc-rcs.el may
want to use rcs2log: it helps to have its name defined in a central
location, instead of forcing everyone to either require vc or duplicate
the definition within syms_of_callproc.
