ppp-test: check if ppp interface is active and IP address correct before starting the test

Browse Source 
Addressing stability of pppos test:
* listing active network interfaces for presence of "ppp0" interface
* fixed IPv6 address regex to prevent ttfw accept partial address only
(less than 8 octets)
* workaround crash after exiting app_main()
