WAZO-1406: add Cisco 88xx

Reviewed-by: https://github.com/apps/wazo-zuul

Why:
The W80 in DECT manager mode (DM) does not use a different product name
in both the User-Agent and in the $PN variable. Thus, the DECT manager
advertises itself as a W80B even though it is written W80DM all over the
web interface. This behaviour is different than the W90, which does the
wanted behaviour.
