message: [lldb] [test/lldb-vscode] Use realpath to match vscode behavior
  Compare the directory paths returned by lldb-vscode against realpaths
  rather than apparent paths.  This matches lldb-vscode behavior
  and therefore fixes test failures when one of the parent directories
  of the source tree is a symlink.
