Make quiet builds really quiet

The change does a couple of things:
- Sets the distutils / setuptools --verbose option to 0
- Sets the distutils / setuptools --quiet option to 1
- The options above end up calling distutils.log.set_verbosity(0)
- Passes the QUIET_BUILD cmake option from setup.py to every
  CMake invocation, when --quiet is passed to setup.py
- Sets the CMAKE_INSTALL_MESSAGE variable to silence messages
  regarding installation of files
- Sets the CMAKE_RULE_MESSAGES variable to disable progress report
  in makefiles when building each source file
- Overrides the CMake message function, not to display
  STATUS / info / untyped messages (still displays warnings and
  errors)
- Changes the build / install elapsed time messages to always be
  printed even in quiet mode
- Reverts the previously introduced set_quiet function in utils,
  because log.set_verbosity() now takes care of silencing those
  messages

As a result, there's a lot less clutter when doing a quiet build.
Warnings, errors and shiboken output is still displayed.
