icmp.sh from selftests.net fails

[Kleber Sacilotto de Souza]

icmp.sh from selftests.net is a relatively new testcase which started to be run on impish (5.13) kernels only in the latest builds after commit "ca3676f94b8f kselftests/net: add missed icmp.sh test to Makefile".

With impish:linux-riscv kernel version 5.13.0-1011.12 the testcase fails with the following error:

This seems to be a flaky test, it has also failed with impish:linux 5.13.0-32.35 after completing successfully during the previous test run.

Ubuntu 21.10 (Impish Indri) has reached end of life, so this bug will not be fixed for that specific release.
