Subject: vm/gvisor: smoke test script: allow specifying gVisor path as env var

The gVisor smoke test script now accepts the `GVISOR_VMLINUX_PATH`
environment variable. When set and non-empty, it will use this path to
find the `runsc` runtime, rather than downloading it from the Internet.

The intent is to use this as part of the gVisor testing pipeline using
a locally-built version of the gVisor runtime (`runsc`).
