MinSeong Kim 6b3d855c39 [CMake] Update GetSVN.cmake to handle repo 
Summary:
When repo is used with git, 'clang --version' option does not display
the correct revision information (i.e. git hash on TOP) as the following:

clang version 6.0.0 --->
clang version 6.0.0 (clang version) (llvm version)

This is because repo also creates .git/svn folder as git-svn does and
this makes repo with git uses "git svn info" command, which is only for
git-svn, to retrieve its revision information, making null for the info.
To correctly distinguish between git-svn and repo with git, the folder
hierarchy to specify for git-svn should be .git/svn/refs as the "git svn
info" command depends on the revision data in .git/svn/refs. This patch
in turn makes repo with git passes through to the third macro,
get_source_info_git, in  get_source_info function, resulting in correctly
retrieving the revision information for repo with git using "git log ..."
command.

This patch is tested with git, svn, git-svn, and repo with git.
