Disable array auto-detection for out-annotated parameters

Disable array auto-detection for out-annotated parameters

If we have a parameter annotated as (out), then having a ctype of
'char **' (or similar) doesn't necessarily indicate an array.

* giscanner/transformer.py: Skip array-detection logic for
  (out)-annotated parameters.
* tests/scanner/annotation.h tests/scanner/annotation.c
  tests/scanner/annotation-1.0-expected.gir
  tests/scanner/annotation-1.0-expected.tgir: Add a test for
  an (out) string parameter.
