package/cups-filters: improve cups-browsed init integration

cups-browsed service is compiled and installed by the package,
but the corresponding services file were not installed for
systemv and systemd.

Specifying --without-rcdir allows to not install the init script
provided with cups-filters, and we provide our own,
Buildroot-compatible init script.

For systemd, we install the upstream-provided service file.
