[PATCH 3/7] selftests/ipc: change ipc test to use kselftest exit codes

[Shuah Khan]

Change ipc test to use kselftest exit codes in kselftest.h
to report test results. With this change this test exits with
EXIT_FAIL instead of -errno. Changed print errno in test fail
messages to not loose that information.
