Fix for problem with undeclared intptr_t type

When building gnu-efi with old compilers with pre C90 compilers:

In file included from gnu-efi-3.0.9/lib/../inc/efilib.h:25:0,
                 from gnu-efi-3.0.9/lib/lib.h:24,
                 from gnu-efi-3.0.9/lib/dpath.c:25:
gnu-efi-3.0.9/lib/dpath.c: In function 'FileDevicePath':
gnu-efi-3.0.9/lib/../inc/efilink.h:145:47: error: 'intptr_t' undeclared (first use in this function)
 #define EFI_FIELD_OFFSET(TYPE,Field) ((UINTN)(intptr_t)(&(((TYPE *) 0)->Field)))

Problem introduced with commit a46a62b12b58139c31d4288384808365c4053bf2
(Fix some types gcc doesn't like).

Avoid this by adding intptr_t (and uintptr_t) typedefs for builds that does
not include stdint.h.
