[PATCH net 7/7] selftests: netconsole: ignore busywait errors

[Matthieu Baerts (NGI0)]

In these netconsole tests, bash is used with errexit (set -e). It means
that if the busywait timeout, the tests finish without printing an error
message.

It is fine to ignore these errors, because the following validate_xxx
helpers will check the content of the output file, and exit with an
appropriated error message, e.g. FAIL: File was not generated.
