Update service name targeted by VTS test

#define LOG_TAG "VtsHalEvsTest"

// TODO:  How should we configure these values to target appropriate hardware?

const static char kEnumeratorName[]  = "EvsEnumeratorHw-Mock";

// Note:  We have't got a great way to indicate which target

// should be tested, so we'll leave the interface served by the

// default (mock) EVS driver here for easy reference.  All

// actual EVS drivers should serve on the EvsEnumeratorHw name,

// however, so the code is checked in that way.

//const static char kEnumeratorName[]  = "EvsEnumeratorHw-Mock";

const static char kEnumeratorName[]  = "EvsEnumeratorHw";

// These values are called out in the EVS design doc (as of Mar 8, 2017)
