selftests/net: enable lo.accept_local in psock_snd test
The psock_snd test sends and receives packets over loopback, and
the test results depend on parameter settings:
Set rp_filter=0,
or set rp_filter=1 and accept_local=1
so that the test will pass. Otherwise, this test will fail with
Resource temporarily unavailable:
sudo ./psock_snd.sh
dgram
tx: 128
rx: 142
./psock_snd: recv: Resource temporarily unavailable
For most distro kernel releases(like Ubuntu or Centos), the parameter
rp_filter is enabled by default, so it's necessary to enable the
parameter lo.accept_local in psock_snd test. And this test runs
inside a netns, changing a sysctl is fine.
