    xen/build: Fix `make cscope` rune
    
    There are two problems, both in the all_sources definition.
    
    First, everything in arch/*/include gets double hits with cscope queries,
    because they end up getting listed twice in cscope.files.
    
    Drop the first `find` rune of the three, because it's redundant with the 
third
    rune following c/s 725381a5eab3 ("xen: move include/asm-* to
    arch/*/include/asm").
    
    Second, and this way for a long time:
    
      $ make cscope
      ( find arch/x86/include -name '*.h' -print; find include -name '*.h' 
-print;
      find xsm arch/x86 common drivers lib test -name '*.[chS]' -print ) >
      cscope.files
      cscope -k -b -q
      cscope: cannot find file arch/x86/efi/efi.h
      cscope: cannot find file arch/x86/efi/ebmalloc.c
      cscope: cannot find file arch/x86/efi/compat.c
      cscope: cannot find file arch/x86/efi/pe.c
      cscope: cannot find file arch/x86/efi/boot.c
      cscope: cannot find file arch/x86/efi/runtime.c
    
    This is caused by these being symlinks to common/efi.  Restrict all find 
runes
    to `-type f` to skip symlinks, because common/efi/*.c are already listed.
