playground: fix the build for gVisor
Exec permissions need to be granted on /tmpfs on Docker in order for
binaries downloaded there to be executable. Additionally, newer versions
of gVisor only create the __runsc_containers__ file in a multi-container
environment, which is not the case for testing.
Updates golang/go#25224
