    xen/arm: unbreak arm64 build for older toolchains
    
    Commit 4941bfb "xen/arm64: macros: Introduce an assembly macro to alias
    x30" moved
    
      lr      .req    x30
    
    to macros.h. A later patch (1396dab "xen/arm64: head: Don't clobber
    x30/lr in the macro PRINT") started to use "lr" in head.S, however, it
    didn't add an #include macros.h to head.S. This commit fixes it.
    
    The lack of alias breaks the build with
    gcc-linaro-5.3.1-2016.05-x86_64_aarch64-linux-gnu. The alias was added
    later to binutils 2.29 in 2017.
