Changed qnetworkreply unittest to work from install directory

- made subdir test depend on echo
- remove SRCDIR and changed to use TESTDATA and QFINDTESTDATA
- added waitForFinish() to handle slow networks
- removed core module header from echo subprogram and replaced
  with needed header only
- Added ipv6 skip to connectToIPV6Address() if not available
- Added check QT_BUILD_INTERNAL and skip tests if backend
  not available
- Skip permission tests if run as root
- Removed win32 debug and release directory locations so that
  application is in known location relative to test data
