selftests: net: disable rp_filter after namespace initialization 



Some distributions enable rp_filter globally by default. To ensure consistent
behavior across environments, we explicitly disable it in several test cases.

This patch moves the rp_filter disabling logic to immediately after the
network namespace is initialized. With this change, individual test cases
with creating namespace via setup_ns no longer need to disable rp_filter
again.

This helps avoid redundancy and ensures test consistency.
