Bug#889468: libsane-hpaio: similar story, different model

[Cristian Ionescu-Idbohrn <cristian.ionescu-idbohrn@axis.com>]

Package: libsane-hpaio
Version: 3.17.10+repack0-2
Followup-For: Bug #879719

And the model is a: HP Color LaserJet MFP M281fdw.

After duplicating the [hp_color_laserjet_mfp_m277dw] configuration
block and modifying it:

-[hp_color_laserjet_mfp_m277dw]
+[hp_colorlaserjet_mfp_m278-m281]

and:

 -model1=HP Color LaserJet MFP M277dw
 +model1=HP Color LaserJet MFP M281fdw

got the scanner working.  The printer driver I use is:

	'HP Color LaserJet Pro MFP M277 Postscript (recommended)'

I also used the advice here [1]:

	$ snmpwalk -Os -c public -v 1 <ip> 1.3.6.1.4.1.11.2.3.9.1.1.7.0

to identify what the block header name should be:

	HP ColorLaserJet MFP M278-M281 -> hp_colorlaserjet_mfp_m278-m281

I'd also like to refer to [2], I found on my way to a solution.

I should also mention that I don't use systemd as init and the avahi
packages are just dependencies I _have to_ keep:

libavahi-client3:amd64		install
libavahi-common-data:amd64	install
libavahi-common3:amd64		install
libavahi-compat-libdnssd1:amd64	install
libavahi-glib1:amd64		install
