Add a regression test for an errcheck replacement when OUT parameters are present.

The existing errcheck tests call a function with no paramflags, so no OUT buffers exist on that path. No test in the inspected test sources sets paramflags with an OUT parameter and an errcheck replacement. A change that restores OUT extraction before the errcheck check would leave these tests passing.

Add a test that defines a function with a pure OUT parameter (PARAMFLAG_FOUT) and an errcheck that returns a replacement value. Assert that the call returns the replacement. The existing errcheck assertions run only on non-posix hosts, so place the new test where the target CI hosts run it.

The early return in build_result is correct. This is a regression-test gap, not a runtime defect.
