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)
