efi: Make const array 'apple' static

Don't populate the const read-only array 'buf' on the stack but instead
make it static. Makes the object code smaller by 64 bytes:

Before:
   text	   data	    bss	    dec	    hex	filename
   9264	      1	     16	   9281	   2441	arch/x86/boot/compressed/eboot.o

After:
   text	   data	    bss	    dec	    hex	filename
   9200	      1	     16	   9217	   2401	arch/x86/boot/compressed/eboot.o

(GCC version 7.2.0 x86_64)
