print/hplip(-plugin): update to 3.22.2

- Convert post-patch to real patches because they are easier to
  maintain.
- Fix a NULL dereference in the scanner backend when D-Bus isn't
  running.
- Depend on sysutils/py-distro to make hp-toolbox (Device Manager) work
  again.
- Upstream switched to Avahi for mDNS support.  Rename the SNMP option
  to NETWORK because it's not just SNMP now.
- Don't install some programs related to uninstalling and upgrading of
  HPLIP and the installation of firmware plugins because they circumvent
  the package system.
- Install icons in share/icons so desktops can choose an appropriate
  resolution.
