ROCR Build ID support

Build system/Package maintainer:
-    BUILDID is specified at cmake.
-    USAGE: cmake -DBUILDID=<ID> ../src

For developer builds the who typically don�t provide BUILDID, cmake will:
-    Determine the last git commit when this tree was syncd 
-    Deteremine the build date 
-    Check if tree is clean when built 

The idea of this embedded string is that later when you get a ROCR build, you can get some idea on the build origination by using: strings libhsa-runtime.so.1 | grep �ROCR BUILD ID�

For eg:
-    If it�s a Jenkins build 25, it returns: �ROCR  BUILD ID: 25�
-    If it�s a developer build sync'd @ 06f5f2a with modifications, it returns: �ROCR BUILD ID: 06f5f2a-2016-04-11-0"
