selftests: net: use setup_ns for SRv6 tests and remove rp_filter configuration
Some SRv6 tests manually set up network namespaces and disable rp_filter. Since the setup_ns library function already handles rp_filter configuration, convert these SRv6 tests to use setup_ns and remove the redundant rp_filter settings.
