[cmake] Build gtest from LLVM when building standalone 

Include the gtest utility directory from LLVM sources when performing
a stand-alone build of LLDB. This is necessary to have a correct gtest
library to link tests against, as the one used by LLVM is not installed
(and not supposed to be). This is the same approach as used in clang.
