udev-extraconf: fix network.sh script did not configure hotplugged interfaces

Browse Source 
Udev script network.sh is called when a new ethernet interface is plugged (eg. USB).
Due to some (old) missing files, this script does nothing, instead of configuring the
interfaces with ifup.
I just commented the corresponding lines to allow the script to reach the part where
it calls ifup.

(From OE-Core rev: cf881c1b96bf93a8a36b7d6ac83aa053ee059ba6)

Fixes [YOCTO 15616]

network.sh relies on (long) missing files (eg. /etc/network/options,
/etc/init.d/network) to decide if it should configure the new network
interface (ifup) or put its name in /etc/udev_network_queue for future
initialization by /etc/init.d/network service.
The actual result was that the new hotplugged interface was never
automatically configured.
Removing the obsolete tests allows the script to do its intended job.
