net-print/cups: drop cyclic dependency on cups-filters

It is a PDEPEND which forces installing both, and makes building a
modular cups-filters more challenging.

Additionally, many "users" of cups may not actually want cups-filters at
all.

- A primary reason is because cups provides libcups, which other
  packages need as an RDEPEND in order to support USE=cups while not
  having any expectation of using a printing stack (at least, yet).

- Even more fun, sometimes users have -bin packages where upstream has
  built the binaries against libcups on the assumption that users who
  want cups support will automatically get it and users who don't want
  cups support "just" need the debian libcups2 split binary package.
  This isn't really solvable without providing a minimal libcups-only
  experience.

Rely instead on a metapackage for the full cups experience.
