Subject: [PATCH] Add environment variable support for testability library use.

Add the option to load the testability library based on whether
an environment variable QT_LOAD_TESTABILITY is set, in addition
to the current "-testability" flag.

This improves the use of testability library together with the
autopilot functional testing tool.

Task-number: QTBUG-32974
