EmulatorPkg: Unix: Use XCODE5 and lldb if Xcode 5 is detected

The EmulatorPkg build.sh will use XCODE5 if that is the default toolchain, and
default to using lldb if Xcode 5 is dectect. This will work for Xcode 6 and
possibly future version of Xcode too.

/usr/bin/clang is just a wrapper that calls the currently selected Xcode
version. xcode-select is used used to display or set the current version of
Xcode used by the command line tools.
