QTestLib: allow for non-zero values in env variables

Browse Source 
The usual behavior for env variables is that any nonzero
value means "enable", so do the same for a couple of QTestLib
env vars. While at it: document them.

\section1 Qt Test Environment Variables
You can set certain environment variables in order to affect
the execution of an autotest:
\list
\li \c QTEST_DISABLE_CORE_DUMP \br
Setting this variable to a non-zero value will disable the generation
of a core dump file.
\li \c QTEST_DISABLE_STACK_DUMP \br
Setting this variable to a non-zero value will prevent Qt Test from
printing a stacktrace in case an autotest times out or crashes.
