torture: Change KVM environment variable to RCUTORTURE

The torture-test scripting's long-standing use of KVM as the environment
variable tracking the pathname of the rcutorture directory now conflicts
with allmodconfig builds due to the virt/kvm/Makefile.kvm file's use
of this as a makefile variable.  This commit therefore changes the
torture-test scripting from KVM to RCUTORTURE, avoiding the name conflict.
