gthr-vxworks.h (__ehdtor): Fix memory leak.

Browse Source 
* gthr-vxworks.h (__ehdtor): Fix memory leak.  The delete hook
        runs in the context of the deleter, not the deletee, so we must
        use taskVarGet to find the correct memory to free.
        (__gthread_key_create): Initialize the task
        variable subsystem so that the task variable is still active when
        the delete hook is run.
