testenv: podman: disable send_redirects

When starting podman, set the following sysctls to avoid ICMP redirects. ICMP redirects lead to test failures (TC_pdp4_clients_interact in the GGSN testsuite), and should not be sent in the test environment in general.

net.ipv4.conf.all.send_redirects=0 net.ipv4.conf.default.send_redirects=0

It is really needed to set both "all" and "default", or otherwise ICMP redirects still show up. I've seen setting both in this patch: https://patchwork.kernel.org/project/linux-kselftest/patch/1570719055-25110-...
