[Buildroot] [PATCH 1/1] package/avahi: allow disabling default services

[Florian Larysch <fl@n621.de>]

By default, Avahi installs service definitions for SSH and SFTP, but
those might not be present on all systems. Add an option for disabling
them.

As there is no way to tell the Avahi package not to install the service
files in the first place, we have to manually remove them from the
target directory.
