selftests/net: convert fib_tests.sh to run it in unique namespace 

Here is the test result after conversion.

 # ./fib_tests.sh

 Single path route test
     Start point
     TEST: IPv4 fibmatch                                                 [ OK ]

 ...

 Fib6 garbage collection test
     TEST: ipv6 route garbage collection                                 [ OK ]

 IPv4 multipath list receive tests
     TEST: Multipath route hit ratio (1.00)                              [ OK ]

 IPv6 multipath list receive tests
     TEST: Multipath route hit ratio (1.00)                              [ OK ]
