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.

-Use a dynamically allocated port instead of binding port 5353.  The bind(2)
-call fails when Avahi has already claimed port 5353.  On top of that, HPLIP
-only performs one-shot queries and those shouldn't be using port 5353 according
-to RFC 6762.
-
-Don't disable loop-back.  It's harmless.
-
-Use default TTL of 1.  RFC 6762 requires 255 for responses, not for queries.
-
-There's no need to join the multicast group for one-shot queries.  Responses
-are sent to the unicast address.
