Bump PKGREVISION on packages depending on CUPS

This should be the last part of the renaming operation for print/cups to
print/cups-base.

Rationale: packages depending on CUPS but not relying on a functional
printing setup only need to depend on print/cups-base (equivalent to the
former print/cups). The new print/cups now depends on print/cups-base
and on print/cups-filters, thus directly providing a functional printing
setup. This bump reflects this change of dependency.
