Hello build bot (Jenkins), Edward O'Callaghan,

I'd like you to reexamine a change. Please visit

to look at the new patch set (#3).

tests: use MOCK_FD instead of NON_ZERO

With this change the mocks are able to return a non-negative value for
the file descriptor expected from open operations. This avoid issues
with subsequent error checks of the form `if (fd < 0)`
