tests: Fix fread wrap to return success by default

Successful return value for fread is the number of items read, and
default behaviour for all wraps is to return success.

This worked previously because all existing tests have custom mocks
for fread, so default behaviour hasn't been used. However next patch
in this chain adds new test which needs default fread wrap.
