selftests: net: add ipv6 RA route to ECMP merge test
As commit bbf4a17ad9ff ("ipv6: Fix ECMP sibling count mismatch when
clearing RTF_ADDRCONF") pointed out, RA routes are not elegible for ECMP
merging.
Add a test scenario mixing RA and static routes with gateway to check
that they are not getting merged.
