Fix crash when querying a runtime config that is defined in environment
Fix crash when querying a runtime config in case when there's no
skia.conf file and the config variable is still defined in the
environment.
Runs the added SkRTConf::UnitTest test as part of new "UnitTest" test.
Previous version of the patch failed Windows build due to setenv usage.
On Windows, use _putenv_s instead.
