Remove VTS_ROOT_PATH.

We don't need to consult a separate path anymore because these tests
statically include their passthrough impl, like this:

    // Allow dlsym'ing self for statically linked passthrough implementations
    ldflags: ["-rdynamic"],

    // These are static libs only for testing purposes and portability. Shared
    // libs should be used on device.
    static_libs: ["android.hardware.tests.msgq@1.0"],
    whole_static_libs: ["android.hardware.tests.msgq@1.0-impl"],

So, since it is no longer needed, removing this user/userdebug
difference.
