uic-Autotest: Remove SRCDIR-define, add stdout-test.

- Replace SRCDIR define by QFINDTESTDATA, simplify code.
- Introduce a test for stdout mode that verifies the newline
  convention.
- Use a temporary directory as not to clobber the
  test directory and introduce an environment variable
  UIC_KEEP_GENERATED_FILES to keep them for error
  analysis.

Task-number: QTBUG-26730
