mem/oom: fork may fail before test

On systems with small RAM and vm.overcommit_memory == 2,
the system may already be in state where Committed_AS is
larger than CommitLimit due to various backround daemons
(NM, tuned, polkitd,...) asking for big allocations.

In such instances oom testcases report TBROK on very first fork.
This patch allows this to be a valid outcome (TPASS).
