selftests: forwarding: Handle 0 for packet difference in multipath tests
If the packet stats have a difference of 0, the test output shows:
INFO: Expected ratio 2.00 Measured ratio
Runtime error (func=(main), adr=9): Divide by zero
(standard_in) 2: syntax error
(standard_in) 1: syntax error
./router_multipath.sh: line 187: test: : integer expression expected
TEST: Multipath [FAIL]
Too large discrepancy between expected and measured ratios
Handle the 0 and display a cleaner message:
INFO: Running IPv6 multipath tests
TEST: Multipath [FAIL]
Packet difference is 0
